An injury expert has given his verdict on how long Kai Havertz could be sidelined after sustaining a knee injury, with footage of the incident now emerging. The attacking midfielder was expected to play a key role for Arsenal this season following his remarkable physical transformation earlier this year.

Arsenal are actively exploring the transfer market to potentially reinforce their attack and cover the absence of the 26-year-old.

Arsenal forward Kai Havertz is expected to miss time due to a knee injury, according to The Athletic.

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.

Arsenal are expected to first look at the loan and bargain basement markets if Kai Havertz is ruled out for a prolonged period of time with a knee injury.

Arsenal forward Kai Havertz is set for a spell on the sidelines after suffering a knee injury, sources have told ESPN. The 26-year-old missed an open training session at Emirates Stadium on Wednesday but it is currently unclear how severe the issue is.

Arsenal had an open training session at the Emirates on Wednesday before their first home fixture of the Premier League season when they host Leeds United on Saturday. Ben White and Kai Havertz were glaring omissions. White came off in the 71st minute in the win at Manchester United on Sunday and Havertz started the game on the bench.

Havertz, who earns £250,000-a-week at the Emirates Stadium, was Arsenal's main man in attack last season, but he's since been joined by Viktor Gyokeres as another option for the centre-forward position. As a result, Havertz was on the bench against Manchester United at the weekend, with Gyokeres leading the line for the Gunners.
