Denis Irwin was full of praise for Daley Blind after the 25-year-old's outstanding display in the Premier League victory over Tottenham, telling the official Man United website that he wouldn't be surprised if Louis van Gaal went with the Dutchman again at left-back.
Irishman Irwin is arguably one of Manchester United's greatest ever full-backs, making over 500 appearances in a 12-year career where he won seven Premier League titles and countless other cup trophies.
Irwin at left-back was one of Sir Alex Ferguson's nailed-on selections for over a decade, so the Cork-born former pro is more qualified than most to judge who should start against Liverpool in Sunday's six-pointer at Anfield.
And 49-year-old Irwin was so impressed with the way the United defence dealt with Tottenham in last Sunday's superb 3-0 win that he suggests the Manchester side could well go with an identical back four against their fierce rivals - a selection that would see Blind continue at the back.
Blind made his first start of the season on the left of the defence against Spurs, having mainly featured as a defensive midfielder for United this year. He put it in a superb performance that nullified the three men he came up against, with Andros Townsend, Nacer Chadli and then Erik Lamela all struggling to cause a problem for the Netherlands international.
"He's a player who reads situations very, very well, I thought he played extremely well on Sunday [against Spurs]," Irwin told the United website. "It'll be interesting to see the team the manager picks against Liverpool, but it wouldn't surprise me if he picks the same 11 players, because they played so well."
Irwin indicated that players returning from suspension and injury may miss out given the quality of the defensive showing against a side trying to catch up with United's fourth-place position, something Liverpool are also trying to do.
"That's the manager's decision and he's got one or two back from suspension and injury, but I thought the team played very well on Sunday.
"Daley's a good, honest pro. He can play at centre-half if you need him to, left-back if you need him to, and obviously he's played mostly in midfield for us this season. I think he's been a really good signing.
"I've got to say he played very, very well at left-back on Sunday, as did the defence as a whole."
