"He (Greenwood) will play, I think he can play centre-forward, I think he can play left-wing, I think he can play right-wing.
"To me, not signing a right-winger thinking he would be out of the team is not the right way to look at it.
"Manchester United have always signed great players to challenge other great players in positions. Manchester United had four centre-forwards in 1999.
"Sir Alex Ferguson signed Dwight Yorke having already had Andy Cole, Ole Gunnar Solskjaer and Teddy Sheringham at the club. It didn't stop him signing Dwight Yorke.
"You don't just say 'where will he play?'. Great players will challenge each other, they'll improve, they will find a way to get into the team.
"They won't feel belittled by it or challenged to the point where they sulk, they will step up to the task and they will go for it.
"I'm sure that's what Mason Greenwood will do. He's still young but so exciting it's untrue. I love watching him."
"I think they need a winger. I think they need a centre forward, I think they need a centre back, they need a proper challenge for David de Gea and then at left-back, they maybe need something if Luke Shaw gets injured.
"For me, they need four or five players still to challenge, whereby they can get into a position where they can challenge for a title and win in Europe – that’s where the club needs to get to."
