Arsenal have been hit by injuries to key players up front and there are growing concerns about Kai Havertz's suitability in the role.

Arsenal striker Gabriel Jesus will undergo knee surgery after injuring the anterior cruciate ligament (ACL) in his left knee. Jesus picked up the injury last weekend during Arsenal’s defeat to Manchester United in the third round of the FA Cup.

Gabriel Jesus has suffered a serious knee injury which could force Arsenal to change their transfer plans in what remains of the January transfer window. The Brazil international was carried off on a stretcher following a collision with Bruno Fernandes during Sunday’s FA Cup third round defeat.
