Gabriel Jesus has undergone surgery on his knee. The Brazilian suffered the injury whilst playing with his country at the World Cup and has since come home and undergone tests with Arsenal.
Suspected damage to his medial ligament was the reason for the procedure. Arsenal released a statement which however did not provide any insight on the possible return date of the striker.
This is far from the first time that Arsenal have lost players during key moments of a season. The injury record of the club up until this point had been relatively good with only Oleksandr Zinchenko, Mohamed Elneny and Emile Smith Rowe missing extended periods; although there is some hope Jesus may not miss as many games as the latter pair.
