Gabriel Jesus was forced to miss Arsenal’s Emirates Cup clash against Monaco on Wednesday after suffering a new knee injury.
The news was confirmed by the club – but the extent of the forward’s injury is not yet known – and the knee problem will now be ‘assessed’ by the Gunners.
It is concerning for the north Londoners he picked up at the .
Jesus had been in good form during , with Arsenal looking to make a flying start to their  campaign after painfully missing out on the title last term, but the Brazil star could now be set to miss the start of the season.
Jesus has registered 11 goals and eight assists across 33 games for Arsenal since he joined the club from Manchester City last summer.
His absence against Monaco provided an opportunity for Eddie Nketiah, who has been waiting in the wings behind the 26-year-old.
Mikel Arteta even decided to hand 24-year-old Nketiah the captain’s armband against Monaco , with former boss Arsene Wenger spotted watching on in the stands.
Nketiah stepped into the Arsenal XI when Jesus was out injured with his knee problem last season.
Arsenal signed Kai Havertz this summer, who can operate as a centre-forward, but Arteta has been reshaping him as part of a midfield three.
The Gunners could also turn to Folarin Balogun following his impressive goalscoring form on loan at Reims last season, although he has been linked with a summer exit.
