Arsenal manager Arsene Wenger questioned the amount of stoppage time as his title-chasing side were held to a damaging 1-1 draw by Liverpool.
A Robin van Persie penalty put Arsenal ahead in the 98th minute but there was still time for Dirk Kuyt to level from the spot four minutes later.
"We conceded a penalty after 11 minutes when the referee said there was eight minutes of injury time," said Wenger.
"I don't see where those three minutes came from and it was no penalty."
The bulk of the injury time was actually added on because of an injury to Jamie Carragher during the second half, the Liverpool centre-back having to leave on a stretcher after a clash of heads with team-mate John Flanagan.
And initially the extended playing time appeared to have worked in Arsenal's favour as Van Persie slotted home what seemed likely to be a much-needed winner from the penalty spot for the Gunners after Jay Spearing fouled Cesc Fabregas in the area.
But Arsenal right-back Emmanuel Eboue was deemed to have fouled Lucas Leiva at the other end allowing Kuyt to score and in the process leave Wenger's side six points behind Premier League leaders Manchester United with six games - including a clash between the top two on 1 May - remaining.
But Wenger, who confronted referee Andre Marriner and his assistants as they left the pitch, suggested his team would be closer to United in the table but for refereeing decisions in recent matches.
"We have been badly done in recent games [at home]," added the Frenchman. "Against Sunderland [a match that finished 0-0] we scored a regular goal and were not given a penalty that was 100%, then today we got caught back like that.
"It is a period where we have not had the biggest luck, that's for sure."
Wenger continued: "We dropped two points. It was a difficult game against a Liverpool team who basically only defended.
"Maybe we are a bit jaded physically. You could see that some players have played 45 minutes and maybe we lack a change of pace, but we tried very hard.
"The players are very disappointed. Who wouldn't be?
"It is about us winning our games. The hope is always there but, to keep the hope alive, it is up to us to win our games.
"We are on a 15-game unbeaten [Premier League] run, but recently we have not taken enough points.
"Now we must give everything until the last game of the season and see if it is our year or not."
Liverpool manager Kenny Dalglish praised the battling spirit of his players as they moved two points clear of city rivals Everton in fifth place.
"I don't think there's another team anywhere that would show the attitude and commitment we showed out there," said the Scot.
"They went through a wee bit of adversity, losing Fabio Aurelio early on and putting a 17-year-old Jack Robinson on at left-back.
"Losing the captain [Carragher], having a right-back in John Flanagan who's only 18, losing a centre forward, losing a goal eight minutes into injury-time, and they still didn't want to accept they weren't going to get anything from the game.
"I don't think I can speak any higher than that. Everybody will be sat there proud at having seen their team produce a performance like that with the attitude and commitment."
Meanwhile, Carragher, who was captaining the side, declared himself "absolutely fine" despite being knocked unconscious in the clash with Flanagan.
"I can't remember anything. As soon as I came round I was absolutely fine," said the 33-year-old.
"It was a little clash of heads and these things happen in football."
He added: "I watched their penalty in the dressing room and then saw that we got our own.
"I was just praying that we scored because to get four points out of six from the last two games is fantastic [Liverpool having beaten Manchester City 3-0 in their previous match].
"I went out on to the pitch at the end because I wanted to celebrate with the lads.
"Some of the players we had out there, because of the injuries we had, still qualify for the youth team, so it was a really good team performance."
