Havertz missed significant time last season with a hamstring injury as Arsenal struggled to close a gap to Liverpool resulting in a third consecutive runners-up finish. The 26-year-old returned before season’s end in a limited role and looked lively in preseason. After his second-half cameo at Old Trafford, he’s at risk of another spell out.

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.

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.
