Manchester United manager Jose Mourinho was full of praise for Eric Bailly after the defender impressed on his first official game for the club.
The Ivorian produced a very solid defensive performance against Leicester City as the Red Devils battled past the Foxes for 2-1.
The Portuguese admits that there is always a question mark hanging over the head of new players but the 22-year-old passed the test with flying colours.
"Eric [Bailly] is working since day one," Mourinho told reporters.
"He started the pre-season with us, he played matches, he's fit so I knew that with him it's just a question of his personality allowing him this big move from Villarreal to Man United to Wembley.
"It was just that.
"I know the player he is but you always have a little question mark when a player comes from a completely different level and plays his first match for Manchester United officially at Wembley with these responsibilities, without Smalling.
"The way he played I think he was really good but I have to say Daley also gave him the stability he needs.
"He was super comfortable so no doubt that he's a man for us."
