Arsenal have been dealt a blow with a Paris Saint-Germain star returning to training ahead of their crucial Champions League semi-final second leg clash.
The Gunners are up against it in their bid to reach the final of Europe's premier competition, trailing 1-0 and having to go away from home and try and overturn the deficit.
PSG have proven themselves to be one of the form teams in the competition, beating the likes of Liverpool and Aston Villa on their ways to the last-four, where they were drawn against another English club.
