Petr Cech is unsure if his Arsenal contract will be extended beyond this season, accepting performances will be key to securing a new deal.
Cech has managed to prevent new signing Bernd Leno from breaking into the Arsenal team since the German joined in pre-season, despite becoming a target for criticism.
The 36-year-old has been unconvincing and struggled to adapt to the demands of new coach Unai Emery, who wants the Gunners to play the ball out from the back.
Emery has supported his goalkeeper and insisted at the start of September that the former Chelsea man is doing as requested.
