Zezti: He just couldn't get the players acting like a team so had to happen. Would like Tuchel or similar next for Everton.

When Ronald Koeman took the acclaim from Goodison Park at the end of his first season as Everton manager, he could reflect with satisfaction on a job well done.
That promising day in the spring seemed an age away on Sunday as Koeman's Everton trooped off the pitch at a largely deserted Goodison Park, with the derision of the fans ringing in his and his players' ears after a 5-2 thrashing by Arsenal that left them in the relegation zone.
This was not what he or Moshiri planned after more than £140m worth of summer outlay - and Koeman was sacked only nine league games into the season on Monday.
Malcolm Bradbrook: Sacking of Koeman seemed inevitable from the day he announced that Lukaku should go to a bigger club
Hymix Big Beard: It's sad, but with a win percentage like his and no signs of improvement or tactical awareness, of course it had to happen.
AtourTB: How can anyone say Koeman's sacking is unjustified? Their results this season have been terrible. Not just losing. Losing BADLY
And here's Koeman's tweet from last night. There's one or two choice replies in there...
I'll miss him simply tweeting 'Matchday' whenever Everton play. It's the little things in life.
Alex Ray: Anyone questioning RK sack have obviously not watched #efc so far. Walsh also accountable for lack of fundamental signings.
This is what Ronald Koeman had to say yesterday after he was asked about Everton's struggles, and his own position.
He said: "The team is underperforming, it is in a difficult situation mentally and struggling for confidence. That is what we need to change.
"I told the players that I believe in the players, I believe in the commitment of the players.
"I still believe I can change the whole situation, but everybody knows how it works in football. That is all I answer about this situation.
"The final result is really poor, but all these kind of decisions (about the future) are not in my hands.''
Nikul: The only man who can take Everton forward now is Gordon Strachan. Bring him in immediately.
Paul Corrigan: We need a marquee manager. Dyche, Unsworth, Moyes, Allardyce would all be a massive show of mediocrity.
For the past few days, there's been mention of David Moyes returning to Goodison Park.
Here's Match of the Day 2 Extra pundit Leon Osman on that very possibility.
Things move quickly - The Telegraph are already reporting that Burnley boss Sean Dyche is a potential target to replace Ronald Koeman.
Dyche has also been linked with the vacant manager's job at Leicester City. He's a popular bloke...
The paper also reports that there's "an expectation" former player David Unsworth will move up from his role as the club’s Under-23 manager to take over in the short term.
John Wilson: Never right to sack a manager but it was like the Mike Walker days. Ancelotti hopefully now or Unsworth/Ferguson short term
£45m on Gylfi Sigurdsson, up to £30m on Burnley's Michael Keane, £30m on keeper Jordan Pickford and £23.6m on Davy Klaassen. Oh, and Wayne Rooney.
Altogether, they spent £140m in the summer. Hmm.
Although, looking at those numbers from another angle...

Koeman is the third managerial casualty of the season, after Frank de Boer left Crystal Palace and Craig Shakespeare was sacked by Leicester.
Below is the record of permanent Everton managers over the past 27 years. Koeman has the second best win percentage.
Here is Ronald Koeman's final Match of the Day interview after yesterday's 5-2 home defeat by Arsenal.
He said then that he believed he could turn Everton's fortunes around...
Tobias Xavier: Guides Everton to Europe, club sells Lukaku - embeds new strategies and juggling with twice the schedule of games. Unfair sack.
Here's the statement confirming Koeman's departure.
He leaves with Everton 18th in the Premier League, having taken eight points from their nine league matches.

Prince Gyimah: I could only master strength to work after that awful defeat to Tottenham only because most of my colleagues are United fans
That gives us an excuse to use the best genre of football picture - miserable manager stood in the pouring rain.
BBC 5 live rugby union reporter
Gregor Townsend has learnt from Manchester City manager Pep Guardiola as he looks to build a Scottish team full of "work-rate, energy and speed".
Townsend is preparing for his first autumn campaign as Scotland head coach, having succeeded Vern Cotter in May.
And the former fly-half says he is inspired by the methods of ex-Barcelona manager Guardiola, who led the Spanish club to 14 trophies in four years.
"I believe people watch Guardiola's attack more than his defence," he told BBC Radio 5 live's Rugby Union Weekly podcast.
"But his teams at Barcelona had a rule to win back the ball. They started at seven seconds, and then it went down to three seconds."
Stewart: As a Scotland supporter, I really hope Everton sack Koeman and hire David Moyes again.
Paul: If Koeman wanted all the mediocre players he's signed without addressing the lack of a decent no.9, then he has to be binned.
Arsene Wenger has taken his fair share of flack in the past few weeks, so here's a few stats to cheer him up.
Plus, Arsenal won on his birthday. What more could he ask for to celebrate his 68th?
- Arsenal have beaten Everton more times than any other club have beaten another in English Football League history (95 wins).
- Arsenal have now scored 100 Premier League goals against Everton, the first time a club has reached the landmark against one team.
Yesterday's result for Everton has been coming,even at 1-0 up you are never confident, we are not going play teams like arsenal every week granted but Brighton Burnley Atalanta Lyon ???? £150 million spent £45 on a player playing out of position. Get Duncan Ferguson and David Unsworth in joint charge to get some passion back.
Bournemouth manager Eddie Howe spoke to the press earlier today, before his side's Carabao Cup match against Middlesbrough on Tuesday.
Howe told reporters: "We'll have hesitation about changing the team [from the victory over Stoke]. In the last round we rotated and we came through the game and played very well.
"We played some good stuff at Stoke at the weekend. In the second half we showed resilience and did very well to see the game out.
"From leading positions we've lost points before, but I've never doubted the character of the players. It was good to get the win."
The Fifa's Best Awards are being held tonight in London.
There's the usual list of suspects but there's a few names you may not have heard of, including Venezuela's Deyna Castellanos.
She's nominated for the best female player - yet does not play in a professional league. In fact, she's never featured in an under-20s international tournament, never mind a senior one.
Andy White: Koeman is a good manager and Everton are a great club. Seems sad that a divorce is on the cards.
Nick Hughes: From an #LFC fan in a family of blues, #EFC need to sack Koeman & hire Tuchel, he's perfect. Then a striker & winger like Gray
Everton manager Ronald Koeman is expected to be in charge for Wednesday's Carabao Cup fourth-round tie at Chelsea.
Despite speculation over his future after Sunday's 5-2 home defeat by Arsenal, the Dutchman took training as normal on Monday.
The Toffees are 18th in the Premier League and have won just two of their nine league games this season.
"I still believe I can change the whole situation," Koeman said on Sunday.
Here's an Everton stat that starts negatively and ends positively. Well. In a way.
- This is Everton's worst points tally (8) after nine games of a Premier League season since 2005-06 - when they had four points but finished the campaign in 11th place.
Martin Davies: Koeman has three games left. If no improvement, change him for Ancellotti or Thomas Tuchel. Not Moyes. Going back doesn't work.
Mikey Holloway: Koeman should be going now. Failed to find a ST. 3 Number 10s. Not playing wingers. Playing ppl out of position
There's been talk of ex-Everton manager David Moyes returning to Goodison Park, where he spent 11 years before his move to Manchester United in 2013.
Here's what the MOTD2 gang had to say about a Moyes return.
Here's what Steve Claridge had to say on Everton yesterday.
