Manchester United fullback Luke Shaw hailed the performance of Eric Bailly for their Champions League draw at Atalanta.
Speaking after the match, Shaw hailed his defensive teammate for his performance and set him the challenge of maintaining such a high standard in the games ahead.
"He was unbelievable," Shaw told MUTV after the draw.
"I think he hasn't had many chances and of course it is tough, it is not easy for someone to not play for that long and to come into a game like this; the way they pressed, at their home place, a very difficult game.
"He was incredible, a big well done to him for the way he has been over the last few months. He has trained well, trained hard and patiently waited for his chance.
"I think he took it tonight really well and I think that is the level now for him, he needs to show day in, day out and of course in the next game."
