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

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.
