The 48-year-old admitted Taarabt has stepped out of line in the past but at the moment he is happy with the contribution of the Morocco international.
He said: "Adel is a talented young man and that talent is recognised here, we support him but he is a young player and sometimes he makes the wrong decisions.
"There are always consequences when you do that but he is in a good place now and we are pleased with what he is producing and as a consequence we will reap the benefit on the pitch.
"Professional football is a way of life and you have to commit to that and it is fair to say that in the past Adel hasn't made the correct decisions about what he should be doing.
"But I'm very happy with what he is doing at the moment, he is training correctly, training well and having an impact. Obviously he has been injured in recent weeks so that is why I haven't been able to play him but he is back now and certainly in my thoughts for the weekend."
