On Tuesday morning before they headed off to Munich, Arsenal players were pictured training but Lucas Perez was nowhere to be seen.

It seems the forward is out with a hamstring problem (slight):

Yaya Sanogo was also spotted (no, really!) training on his own, away from the rest of the first team.

We still don’t know what is wrong with him. Sidelined all season with a ‘secret problem’ (Arsene Wenger’s words) he has not even been listed as ‘injured on Arsenal.com at any point.

Wenger has also confirmed that David Ospina will start, although why anyone is wasting a perfectly good question at his press conference to ask this is beyond me.
