Arsenal defender Laurent Koscielny is expected to be in the squad for tomorrow's Champions League showdown against Barcelona at Camp Nou.
The Frenchman has been struggling with a calf injury since his side's 3-2 defeat to Manchester United on February 28.
According to Sky Sports News, Koscielny took part in training on Tuesday morning and was part of the team that travelled to Spain.
Arsene Wenger's men have the difficult task of overturning a 2-0 defeat from the first leg of the last-16 tie.
