Arsenal have revealed that Laurent Koscielny is fit enough to be part of the squad for tomorrow's Champions League group match against Borussia Dortmund.

The French centre-back has been out of action since the defeat to Chelsea at the start of October with Achilles tendinitis.

His return will be very welcome at the back, with left-back Nacho Monreal having to fill in at centre-half in recent weeks alongside Per Mertesacker.

Although Koscielny's return is good news for the Gunners, Arsene Wenger confirmed that Jack Wilshere, Wojciech Szczesny and Theo Walcott would all be missing from tomorrow's match at the Emirates.
