Former Cardiff City and Middlesbrough manager Neil Warnock has revealed that he would not swap any of Boro's defenders for Manchester United's.
United and Middlesbrough will face off in the FA Cup fourth-round.
"They've got great individuals but not a team and I don't see that coming," Warnock told talkSPORT.
"They've got my old team, Middlesbrough, in the next round of the FA Cup and I wouldn't swap any of their defenders for the back-three at Middlesbrough – Dael Fry, Anfernee Dijksteel and Paddy McNair.
"I think they're better than Man United's defence."
