The conclusion from Newcastle United’s trouncing of Arsenal in the Carabao Cup semi-final was that Eddie Howe has better attackers at his disposal than Mikel Arteta. William Saliba and Gabriel Magalhaes will have nightmares about Alexander Isak for months after being tormented by the Swede in both games.

“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.
