Havertz has made eight appearances for the Gunners and is still yet to register a goal or assist. If anyone is in need of a confidence boost it is the 24-year-old and the chance to get off the mark against a rotated Brentford side is appealing.
It is going to take time for Havertz to adjust to his new team-mates and Arteta has called for patience.
There have been a few green shoots of promise, most notably against PSV Eindhoven last week when Havertz was given a run up front.
Arteta primarily sees Havertz as a No8 in midfield, but he plans to use him as a striker too given his height.
Brentford often revert to a back-three when playing one of the Premier League’s top teams and, as such, Havertz’s size will come in handy.
The back injury picked up by Declan Rice during Sunday’s north London derby isn't serious, but he will not be risked at Brentford. Jorginho and Mohamed Elneny are in contention to play instead, with Fabio Vieira also likely to get minutes.
