Arsene Wenger has ruled out Henrikh Mkhitaryan for Thursday's Europa League semi-final clash with Atletico Madrid.
However, Jack Wilshere and Mesut Ozil, who along with Mkhitaryan missed Sunday's win over West Ham United, could be available.
"Jack had a training session today and he looked positive so he has a good chance to be available for Thursday," said Wenger.
"Ozil was sickness [flu] so I cannot tell you much more about that. We will have to see how he recovers tomorrow [Monday].
"But Mkhitaryan won't be available on Thursday."
