Arsenal boss Mikel Arteta admits an injury concern for Thomas Partey after their FA Cup defeat to Manchester City on Friday night.
A potential injury to Partey could derail a few things for the Gunners though as Arteta confirmed a knock to the ribs in his post-match press conference.
He said: "He had some discomfort and it was getting worse and worse. He could not continue and he was not comfortable to continue. No initial diagnosis. Tomorrow, or the day after it will have to be an MRI scan and we'll see what he has."
On the need to sign a midfielder before the deadline falls, Arteta also said: "Well we have the injury of Mo (Elneny) at the moment and it's not been possible to get him fit. Sambi's (Lokonga) come in and I think done well. That's what we have.
"It's true Thomas is a big influence and is a big personality and player in our squad and in the second half we didn't have him."
