Leicester defender Jonny Evans has backed Harry Maguire to be a Manchester United hit and believes he can have a similar impact to Virgil Van Dijk at Liverpool.
England international Maguire joined United from Leicester for STG80 million ($A143 million) last week, a world record for a defender.
Van Dijk helped Liverpool win the Champions League and finish second in the Premier League last season after his STG75 million ($A134 million) move from Southampton in January 2018.
United kept their first clean sheet since February in Maguire's debut on Sunday - a 4-0 win over Chelsea - and Evans, who won three titles at Old Trafford, tipped him for success.
"You can see comparisons in their games (Maguire and Van Dijk), both are great on the ball, and Harry has got explosive pace people don't see," said ex-United man Evans.
"He is powerful, good in the air ... Everyone will compare the transfer fees but it's so difficult to judge transfer fees nowadays.
"We are all human and it is weird we get traded for money. In the transfer market it's all supply and demand and things can go up and down at any moment.
"The most important thing is for him to be judged on how he plays. I don't have any worries about him there."
Evans also insisted VAR will be a success after it disallowed Leander Dendoncker's second-half strike in Sunday's 0-0 draw with Wolves.
The midfielder's initial header hit team-mate Willy Boly on the arm before he fired in. It took 98 seconds to disallow the goal but Evans believes VAR will work.
"A few of the Wolves players were still trying to debate the decision afterwards and you're saying 'we've got VAR, that's what it's for.' It made the right decision and done its job."
