Arsenal defender Laurent Koscielny is fit to face Barcelona in Wednesday's Champions League clash at the Nou Camp.
The France international has been out of action since suffering a calf problem in the Gunners' 3-2 defeat at Manchester United on February 28.
Koscielny trained with the squad on Tuesday morning before travelling to Spain where Arsenal will attempt to overturn a 2-0 deficit from the first leg at the Emirates.
Manager Arsene Wenger has been criticised by irate supporters in recent weeks after just one win from the last seven matches, the latest setback a 2-1 defeat at home to Watford that ended hopes of a third successive FA Cup triumph.
But Wenger will go into this week's game with no fresh injury concerns after all those involved at the Emirates on Sunday reported a clean bill of health.
However, he is still unable to call on a number of key players: Aaron Ramsey, Petr Cech, Santi Cazorla, Alex Oxlade-Chamberlain, Tomas Rosicky and Jack Wilshere are expected to be out until April at the earliest.
