As Tyrell Malacia and Luke Shaw are still on the comeback trail from long-term injuries, Diogo Dalot has been ever-present on that flank this season, with new signing Noussair Mazraoui deployed on the right side of defence.
However, Mazraoui was withdrawn at half-time of our most recent fixture, the goalless draw at Aston Villa, and he subsequently pulled out of the Morocco squad.
It remains to be seen whether the former Ajax and Bayern Munich defender will be fit to take on the Bees, and Ten Hag is expected to provide an update in his press conference on Thursday but, if he is unavailable, then Jonny Evans or Victor Lindelof could be asked to deputise.
