“Kai has played a lot of football but his robustness and his availability is unbelievable,” Arteta said. “Genetically, he is a powerhouse. He is so well built. He is a player that anything you ask him, he is happy to do: to run, to be very robust, to make long distances. His body absorbs everything.”

Mikel Arteta has described Kai Havertz as a genetic "powerhouse" and backed the Germany international to compensate for Arsenal's failure to sign a forward in January.

Havertz, 25, has faced criticism this season and missed an open goal in Arsenal’s 5-1 thrashing of Manchester City on Sunday.
