Arsenal manager Arsene Wenger has rubbished speculation linking him with Schalke, while ruling out a move for Barcelona’s David Villa.

Wenger’s position is under unprecedented scrutiny as he oversees another disappointing season in north London.

The future of the Schalke coaching role is unclear, with Jens Keller acting as caretaker following the sacking of Huub Stevens in December.

When asked about the rumours tipping him with a switch to the Veltins-Arena, Wenger said: “I am totally committed to this club (Arsenal).”

The Frenchman also said the club were not in talks to sign Spain international David Villa from Barca, preferring to rely on his existing squad and expressing a desire for January transfers to be restricted.

“We are not on the case,” Wenger said.

“We want to make things happen from inside the club. We have the resources to do well.

“The gamble (of signing) is much bigger than during the summer. The number of players you are allowed to sign should be limited.”

Wenger used the form of Theo Walcott and French centre-forward Olivier Giroud to justify his decision not to pursue Villa or other new offensive recruits.

“(Walcott) has improved everywhere. His finishing has improved a lot,” he said.

“(Giroud) is developing well and fights for the team.

“(Aaron Ramsey) has a good performance (against West Ham) in a position that I think is made for him. We have to make up some ground. What was important for me was the manner we responded.”

Arsenal travel to face Brighton and Hove Albion in the fourth round of the FA Cup on Saturday.
