The Black Star is set to be out for some time and the Spanish tactician is optimistic the extent of the damage is not as bad as the last campaign.
Arsenal manager Mikel Arteta has revealed midfielder Thomas Partey will be subjected to another scan to know the extent of his injury.
The Ghanaian injured his thigh in training and missed the team's 2-1 Premier League win against Fulham last Saturday at the Emirates Stadium. The former Atletico Madrid star is set to miss another match on Wednesday alongside Oleksandr Zinchenko, who is nursing a knee problem.
"I don't think [the duo will recover in time to play Aston Villa on Wednesday]," Arteta confirmed to the club's website ahead of the fixture.
"We still have to make another scan, especially on Thomas [Partey], to see the length but I do not think they will be available.
"It is a similar area [to the one that kept Partey out last season], but hopefully not as bad."
Last season - on April 4, the 29-year-old injured his thigh at Selhurst Park in a 3-0 loss against Crystal Palace. He went on to miss the rest of the season and his absence was felt by the Gunners who went on to miss out on the Champions League places.
