Arsenal have been given a huge boost ahead of their Europa League semi-final first leg against Atletico Madrid as Diego Costa is 'unlikely' to play.
The deadly striker has been in sensational form since returning to Atletico but Diego Simeone admitted the 29-year-old is losing his race against time.
Arsene Wenger will be buoyed by the news as he pursues a triumphant send off after 22 years in charge of the Gunners.
But Simeone is confident that Costa will be fit again in time for the second leg.
