Arsenal could be handed a major boost ahead of the Champions League semi-final second leg against Paris Saint-Germain after the French side confirmed an injury to Ousmane Dembele.
The in-form attacker scored the only goal in the first leg at the Emirates but his participation in Paris is now in doubt after picking up a hamstring issue.
Dembele was forced off during the second half of Tuesday's clash in north London.
He has been emblematic of the transformation of Luis Enrique's side since the turn of the year and has registered 33 goals and 10 assists in all competitions this term.
