Arsenal announced Gabriel Jesus suffered an ACL injury in his left knee against Manchester United in the FA Cup with the striker set to undergo surgery.

Arsenal's Brazilian forward Gabriel Jesus is set for a lengthy spell on the sidelines after suffering what is suspected to be an anterior cruciate ligament (ACL) injury, according to British media reports on Tuesday.

Arsenal forward Gabriel Jesus will have an operation on his left knee after sustaining an anterior cruciate ligament injury. Jesus, 27, was taken off on a stretcher during Sunday's FA Cup third round defeat by Manchester United at Emirates Stadium. The Brazilian has made 27 appearances across all competitions this season, scoring seven goals.

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

But now, a report from the Mail suggests Arsenal have been offered the chance to sign Paris Saint-Germain forward Randal Kolo Muani and Bayern Munich winger Kingsley Coman in January.
