The injury to Havertz, 26, leaves the Gunners with just one healthy center forward — new signing Viktor Gyokeres — as Gabriel Jesus has yet to return from last season's ACL injury.

Explaining why Arsenal went ahead with Trossard's revamped contract, and the implications for the rest of their transfer business.

Kai Havertz has been ruled out of Saturday’s game against Leeds United, having picked up an injury this week. In Mikel Arteta’s pre-match press conference at the Sobha Realty Training Centre on Friday, our manager was asked for more information.

Arsenal are waiting to see if Kai Havertz is going to be on the sidelines for a period of time after the forward picked up a knee injury. The 26-year-old was not part of the open training session held at Emirates Stadium on Wednesday and the injury is being assessed by the medical department.
