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.

We don’t know any details and so speculation about Havertz’s injury and what Arsenal will do is just that — speculation. Havertz could miss a couple weeks, a month, a couple months, or the rest of the season.
