Arsenal are expected to be without striker Gabriel Jesus when they face Manchester United in the Premier League next month.
The striker picked up an injury with Brazil which has ruled him out of the rest of the World Cup.
The Telegraph report Jesus is facing three months on the sidelines due to his knee injury.
This would rule him out of Arsenal’s home fixture against Manchester United, set to take place on Sunday January 22.
Jesus set to miss Arsenal v Manchester United
This fixture is six weeks away, making it likely Arsenal will be without their first choice striker for the fixture.
They spent £45 million to sign Jesus from Manchester City in the summer, and will be depending on Eddie Nketiah as a back-up.
It is very possible Arsenal now enter the transfer market to sign a replacement. Manchester United are also looking to sign a striker after Cristiano Ronaldo’s departure.
The game taking place in late January means the Gunners will have time to sign a new forward in time for the fixture.
They currently sit top of the league but face West Ham and Brighton at the end of December before the transfer window re-opens.
Manchester United are the only Premier League side to beat Arsenal this season, winning 3-1 at Old Trafford.
United entered the World Cup break in fifth place, recovering strongly after a poor start to the season.
