Gabriel Jesus’ knee injury is “not looking good”, Arsenal manager Mikel Arteta says. The Brazil striker was taken off after 40 minutes in Arsenal’s FA Cup loss to Manchester United on Sunday.

Just when Gabriel Jesus was rediscovering his form for Arsenal, the Brazilian suffered a knee injury that will keep him sidelined for the foreseeable future.

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.
