Arsenal manager Mikel Arteta says Kai Havertz has undergone a "transformation in his body" while being injured and claimed he "destroyed all the metrics we had in the gym for the last 10 years."

This upward trajectory appeared to be reaching the crescendo of Sané signing a new contract. An offer from Bayern Munich is said to be on the table, Sky Germany report, but the German international is yet to put pen to paper, which has given hope to Arsenal and other unnamed English clubs.

Mikel Arteta says there has been a “transformation” in Kai Havertz ’s body during his injury lay-off and the striker has now taken his physique to a “different level” by bulking up. Havertz injured his hamstring in February and the initial diagnosis was that he would miss the rest of this season.
