A video appearing to show Kai Havertz limping badly during Arsenal ’s mid-season Dubai trip has ramped up fears over the forward’s fitness as Mikel Arteta faces an injury crisis in attack.

Arsenal are assessing Kai Havertz after the forward suffered an injury scare during their winter training break in Dubai, sources have told ESPN.
