Wojciech Szczesny's future at Arsenal is in doubt.

The Daily Mail says Arsenal are eyeing Sunderland goalkeeper Simon Mignolet for next month's market.

Arsene Wenger's search for a new goalkeeper to challenge Szczesny has seen him turn to the impressive Mignolet.

The Arsenal manager is unhappy with the level of competition Szczesny has at the moment and wants an experienced keeper to push the young Pole and even replace him.

Pepe Reina, Asmir Begovic and Michel Vorm are other goalkeeping possibilities.
