Havertz will spearhead Arsenal's attack as they bid to overturn a two-goal deficit against Newcastle in their Carabao Cup semi-final second leg on Wednesday evening. "The next stop is a final in Wembley so we know how big that is and you can feel it," added Arteta. "The momentum is with us so now is the the moment to go full gas.

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

“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.”
