Manchester United boss Jose Mourinho was full of praise for new defender Eric Bailly as he compared him to the defenders he managed at Chelsea.
The youngster became the club's first summer signing after his £30million move from Villarreal.
Mourinho was coy about whether the 22-year-old will be a regular straight away in his squad but believes the Ivorian will be a key element in his squad next season.
"I could compare him with some players I’ve had previously but I don’t want to do it because obviously the other boys play for other clubs," Mourinho told MUTV.
"But he is a player who we believe has all the attributes. He is very strong physically and very fast. It’s not so easy to find a fast player when you have quite a big body; he’s a heavy guy, a tall boy who's really fast.
"He comes from a Spanish culture where the first phases are important so technically he’s very good.
"For some periods, he played right-back and, because playing in the right-back position demands more from an attacking point of view, it’s good for a centre-back to play some periods as a right-back.
"My only question mark at the moment is one I have to help him delete – the question mark of someone who has never played at such a big club with so many responsibilities and so many expectations.
"So is Eric ready to come here and start performing from day one? I don’t know. It is a question mark but my job is to delete that question mark as soon as possible and give him the stature, brain and personality to play for Manchester United."
