Arsene Wenger refused to comment on his future as he said Arsenal's 3-0 defeat to Crystal Palace on Monday night was "damaging".
Goals from Andros Townsend, Yohan Cabaye and a Luka Milivojevic sealed the win, leaving the Gunners in sixth place with 54 points, and Palace six points clear of the relegation places, in 16th.
It was the first time Wenger has lost four league away games in a row, and leaves the club's European hopes hanging by a thread.
After the game, Wenger said: "It's damaging of course. On that front that's what is most difficult for us. It has consequences on our top four chances.
"You understand that our fans are very unhappy. You come here in the hope that we win the game.
"Every defeat is a big worry. I've managed over a thousand games for Arsenal Football Club and we are not used to it, so of course it's a big worry."
He added: "We created dangerous situations but defensively we were exposed. I thought it was level in the first-half but they came out stronger in the second half.
"I thought we were a bit unfortunate with the second and third goal. It killed our game."
And asked whether or not he had any comments on his Arsenal future, Wenger said: "No."
