Arsenal midfielder Santi Cazorla is expected to be out for 'a few weeks' after suffering an ankle injury which forced him to miss the 3-1 win at Sunderland.

Cazorla has recently been on international duty with Spain and Arsene Wenger is not anticipating the 28-year-old will return to action before mid-October.

The former Villarreal playmaker's absence merely adds to Wenger's injury concerns ahead of Arsenal's opening UEFA Champions League group game against Marseille on Wednesday.
