The 25-year-old was ruled out of the tournament with a suspected medial ligament damage confirmed and now according to reports, he has now completed his surgery and his set for a recovery phase.
Reports have suggested Gabriel Jesus could be out for up to three months but it is understood Arsenal are not putting a timescale on his return as yet. It is believed that the Brazilian has already returned to England from the Gulf for an assessment and to speed up his recovery in order to play some part in Arsenal’s season-ending game.
An Arsenal statement read: “Gabby will now begin his rehabilitation programme. Everyone at the club is supporting Gabby and will be working hard to get him back on the pitch as soon as possible.”
The news is a problem for Mikel Arteta’s Arsenal, who restart their Premier League campaign on Boxing Day when they host West Ham.
Jesus has scored five goals for the Premier League leaders in all competitions this season after signing from Manchester City in the summer.
The Gunners though have Eddie Nketiah as striker back-up while Gabriel Martinelli can also play in a centre-forward role if required.
