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.

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.

The knee injury suffered by Gabriel Jesus will force Arsenal into the market this month to sign a new striker.That is according to Tuttosport, who report that the Gunners will now make a new push for Juventus striker Dusan Vlahovic to replace Jesus.
