- Arsenal edge to win over battling Hull
- Sanchez scores twice, a late penalty and controversial opener
- First goal went in off striker's hand
- Hull's Clucas sent off for handball on the goal-line
Hull boss Marco Silva told BBC Sport: "The most important thing is the result. It was a very good second half. We had control of it and caused Arsenal problems. They started the game better than us and after the story of the first half they score with handball. We didn't deserve this result.
Was the first goal handball? "My players didn't feel when the referee started the second half and the referee apologised with the handball. After this a really important moment in the game when Markovic had the big chance but this is football and I don't want to talk about this.
"In my mind it is always possible to do better. We need now to rest our players and prepare for the next match."
To be honest, Wenger hasn't told us a great deal there, has he?
Arsene Wenger on his future: "I focus on what is important, winning football games and getting the team to perform. The rest, I cannot influence.
"I have big respect for this country and this club, and I am grateful because I have worked here for 20 years. My job is to make these people happy and when I don't do that I feel guilty - that's why it's important for us to win.
And, in a roundabout way, without actually mentioning the former Arsenal striker, Arsene Wenger was asked about his future (but with no specific reference to Ian Wright)...
Arsene Wenger speaking to Match of the Day: "We were resilient, focused and organised, but a bit with the handbrake on as we were under pressure to win the game. In the end perhaps we were fortunate to get away with a positive result.
"We created really clear-cut chances, quite a few in the first half, but just couldn't finish the game off.
"Hull were impressive today, physically, tactically, and did really well."
Greg: Join the very very long list of clubs who have been Clattenburged, Hull!
Dave Payn: For all his moans about decisions Wenger's Christmases have all come at once. Maybe the praise has gone to Clatts' head.

"No-one has greater admiration for Arsene Wenger than myself. I think it's a privilege for him, and honour, to be able to plot his own exit.
"But I do have concerns that have grown over a number of years. The pressure may be getting to him. When he pushed that fourth official recently I thought it may have become time for him to take a break from the game."

"Arsenal had to win today for Arsene Wenger, but if they lose both the upcoming games in the Champions League and the FA Cup then that will make the situation really difficult. Because there is a doom and gloom around the club."
Arsenal boss Arsene Wenger, speaking to Sky Sports: "I felt we were resilient, focused. It was not easy against a good side. There was an edgy atmosphere but as a player you have to cope with that."
Had good fortune in the win? "Maybe. Sorry for that but I cannot influence that.
"Our job is not to focus too much on what is said and focus on what we are responsible - the performance on the pitch."
Hull defender Andrew Robertson for Sky Sports on the Alexis Sanchez handball controversy: "The referee apologised to us after half-time and said it was a handball. He obviously realises he was in the wrong. It must be tough for him, but often decisions don't go your way when you come to these big stadiums.
"The ref told us he didn't give it because he wasn't 100% sure. Not many referees can admit they're wrong, so it's good when he does though it doesn't make things better."
"Maybe" we had some good fortune, says Wenger. Maybe would be an understatement, Arsene.
Sanchez's first goal, the Gibbs challenge on Markovic - did Wenger see them? He's just appeared...
Hull City boss Marco Silva, speaking to Sky Sports: "2-0 is not the story of the game. We didn't start well in the first half. We lost some balls in important zones. They scored one goal handball. We make mistakes, sometimes the referee make mistakes too. We don't have a good day but that is football.
Should Kieran Gibbs have been sent off? "Yes. It is true. Markovic go to the goal.
"I see positives in the game. I liked how we reacted in the second half. Now we have time to rest and prepare for the next game."
Adam Reid: A blatant handball goal and a penalty given for blatant handball. Hardly convincing for Arsenal.
Arsenal goalkeeper Petr Cech: "There are not many games left to be played, and though Chelsea have a big advantage all we can do is make sure we keep winning our games.
"The table is very congested in the race for the Champions League positions, so this win is exactly what we needed.
"We need to be consistent, because we do have periods where we do well then other weeks when we lose games. We need to improve where we can improve and ensure we are ready for every game, because now every game will be like a final."
More from Kieran Gibbs: "The players do not get too involved in politics, we just want to play football. At the end of the day the most important thing is what happens on the pitch. We have a job to do and that is it."

"I think Arsenal shaded the game. They will have to play far, far better against Bayern Munich next week.
"A slightly unconvincing performance, and of course it was a crucial decision not to send off Kieran Gibbs. It was kindly by Mark Clattenburg."
Arsenal full-back Kieran Gibbs, speaking Sky Sports: "It was a good chance for us to show a response and we did that today. I still think we can play a lot better, we have a squad to cause a lot of damage, we will sharpen up and look even stronger.
"It is the first time I have heard about a hand so I will have to see it again. I am sure a few decisions have not gone our way so I'm not too concerned about that.
"I took a chance with the challenge on Markovic. The ref said the ball was going away from goal."
Former Hull City defender on BBC Radio Humberside
Hull City's performance was strong, and they did really all they could. The referee's decisions have hurt Hull today, but the side are showing they've got a very real chance of staying up.
The history books will say Arsenal won it 2-0, but that doesn't come close to telling the full story. Hull could have got something from that game and it was only in stoppage time that their brave effort was snuffed out.

You've got to feel sorry for Sam Clucas. His keeper has stitched him right up! It was an easy decision for Mark Clattenburg.
And do you want to know the irony? Jakupovic had probably made up the ground and was covering behind Clucas, not that the defender knew.
Finally, the points are safe. Alexis Sanchez slots the penalty, reward for his work in earning it. It was the Chilean who provided the cross for Lucas Perez to head against Clucas's arm. Harsh on Hull, 2-0 flatters Arsenal.
And he had to go. Alexis Sanchez with the ball on the spot...
The irony. Alexis Sanchez handled for Arsenal's goal, Sam Clucas concedes a penalty for handling on the line. Arsenal break, a Lucas Perez header, Clucas handles. No argument about it.
Headed away by Laurent Koscielny
Another Hull corner...
Nick Hughes: Gibbs is being given the run around by Markovic, who's been Hull's best player. Why don't Liverpool want him? Makes no sense.
Ricky Kelehar: This is why Wenger is maddening. Takes our two best players of today off and leaves the utterly ineffectual Ozil on.
Salman Tahir: Hull robbed of the chance to earn a decent point here. Time to revisit 'video support' for officials!
Arsenal have hit the pressure-release button. Some precious time in the Hull half. Nearly time for the fourth official's board...
Arsenal are scrambling. Laurent Koscielny has to reach to dispossess Oumar Niasse. Into the final five. This has been a second-half grind for the Gunners.
Still Hull ask the questions. Yet another cross. Poorly dealt with. Another corner. The Tigers have had seven to Arsenal's three. Diomande! Headed over. Should have hit the target.
All of the action is in the Arsenal half. The home fans look worried. Hull free-kick. The big beasts go to challenge, but it loops into the hands of Petr Cech.
The Hull full-backs are miles up the field. If anything, the Tigers' delivery is just letting them down. Double change for Arsenal. The Alexs - Iwobi and Oxlade-Chamberlain off, Lucas Perez and Danny Welbeck on.
The Arsenal defenders might need helmets for the rest of this game. They will be bombarded. A Hull corner, a diving Oumar Niasse heading wide. In Six Nations season, the up-and-unders will keep coming.
Eamonn McGurk: Desperate times maybe, but I'll take a scrappy 1-0 win against Hull in a 75% full stadium!
Nick Aaron: I can see Hull getting something here. Arsenal extremely wasteful once again.
Arsenal have to ride the storm. Cross after cross from Hull. From the left, from the right, from the left again. Lazar Markovic gets the header in and Petr Cech saves, but this is far from comfortable for the Gunners. Last sub for the Tigers. Tom Huddlestone off, Adama Diomande on.
Just after I praise Alexis Sanchez, he goes in the book for diving. There was a hint of contact from Andrea Ranocchia, but Sanchez made the full three-course meal out of it.
Former Hull City defender on BBC Radio Humberside
"Think how far Hull have come in the past few months. They are now competing against teams like Arsenal, and no longer look like a relegation side."
Alexis Sanchez has been excellent today. There's been chat about his attitude, maybe a sense of frustration from the Chilean, but he's been everywhere, chasing the ball life his life depends on it.
I'm still not having this as finishing 1-0. Arsenal are finding more space as Hull leave the back door open. A Gunners corner is headed over by Shkodran Mustafi. Danny Welbeck is getting loose.
