It is not only results but the manner of the performances which have increased the pressure and while Koeman would not talk about his future, he is confident the squad he has assembled - spending £150million in the summer - will bounce back.

Specifically asked whether he was the right man for Everton, he said: "I don't answer this type of question. That is not the business at this moment.

"I have experience and if you win your life and your day is different. If you lose of course it is not nice if you have two weeks in an international break and get a defeat, but that is life and you have to accept it.

"But I don't accept to sit back and wait. We will continue and I will try to do the best for my job. All the stuff and questions are not in my hand but I try to get the best out of the players.

"If there is no commitment and no aggression that is maybe a reason to think about my future but I thank the players for their commitment.

"I can't complain about my players, they did everything. Maybe we could create more but it is not so easy against Burnley.

"We tried everything; the commitment and spirit of the players was really positive and the final result was not.

"Some circumstances are against the players at the moment and that is really difficult at the moment."

Burnley boss Sean Dyche, whose side won courtesy of Jeff Hendrick's 22nd-minute goal, believes Koeman still has time to turn things around.

"He's a very good manager, a very good club and some very good players," he said.

"We all have tough times - and players have tough times - where you have ups and downs. Sometimes you have collective down-times in the team and it is breaking that and it goes away very quickly.

"If they (Everton) turn up and get a win today it all looks very different. In the Premier League, particularly, one game can change perceptions very quickly.

"We can only worry about ourselves and so far, so good. But there is a long way to go."
