Arsenal boss Mikel Arteta admits they need a fully fit Emile Smith Rowe this coming week.
Arteta hopes Arsenal will be boosted by the return of Smith Rowe as they prepare for Thursday's revenge mission against Olympiacos and Sunday's north London derby with Tottenham.
Smith Rowe has broken into the Arsenal team since Christmas and played a key role in their recent revival, but he has been out of action since February 28 after injuring his hip against Leicester.
“He's close to returning and he's going to have a full session today to see if he can be involved in tomorrow's game," said Arteta.
“After training, we will know exactly where we are with him."
