And, though Hughes was keen to underline the 23-year-old's importance to the squad, he challenged Taarabt to make it impossible to leave him out.
“On the first day of the season we were beaten at home quite comprehensively, and I made changes,” Hughes told the Times.
“Those changes affected Adel. But he’s very well thought of here, this is the best place for him and he will get games.
“He has to bide his time like a number of other players do. There are a number of players waiting to get a run in the team, and they will get that run.
They just need to keep on focusing on working hard on training and making it difficult to leave them out of the team.”
