Arsene Wenger insists there has been no dressing room fall-out with Alexis Sanchez at Arsenal.

The Chile international, whose future is set to come under renewed speculation ahead of the impending January transfer window, scored twice as the Gunners beat Crystal Palace 3-2 at Selhurst Park.

It gave Wenger a win in his record-equalling match as a Premier League manager but he was faced with questions over Arsenal's players showing an apparent lack of desire to celebrate Sanchez's goals.

Wenger, though, went into familiar mode when asked whether there was a fracture in the camp.

"No, not at all. I did not see that," he told Sky Sports. "I am not fearful (of a bid coming in), but that is a subject that will turn up because of his contract situation.

"I have said that many times since the start of the season so I can only repeat what I have said."

Wenger celebrated his 468th win of 810 league games at the Gunners and it came after nervy finish when James Tomkins scored late on for Palace.

Sanchez's double had made it an easy looking evening for Arsenal after Andros Townsend had initially cancelled out Shkodran Mustafi's opener.

"It was convincing, the second half was more difficult than the first because we didn't take advantage of the chances we created," Wenger added. "When you come here it's a difficult game for everybody - to go home with the three points you need to suffer a little bit, and we did that tonight."

Jack Wilshere again impressed and is hopeful of tying up a new deal in the near future.

"I spoke to the boss and he said he will speak to me so we'll see when he speaks to me, I am sure it will be done," he said.
