The Frenchman has emerged as integral part of Jose Mourinho's squad this season, having scored six goals from nine Premier League appearances.
And Bailly says the winger has shown even more impressive skills in training.
"With the talent he has, he's the kind of person who always makes a difference. He has huge talent, Bailly told the club's website.
"In training, you see he has things that nobody else does. I hope he will exploit that and demonstrate his abilities this season."
