The Swede, yet to make a Premier League start this season, came on for the injured Phil Jones in the first half against Huddersfield and looked miserably out of his depth.
He failed to show any resilience in the build-up to Huddersfield’s first goal and suffered a complete lack of basic judgement for their second, missing a header that enabled Laurent Depoitre to round David de Gea and claim what turned out to be the winning goal.
And Redknapp, writing in a column for the Daily Mail, noted that United’s training staff would have to work with him closely over the next week.
“He probably feels the manager does not rate him and it is vital that Manchester United coaches work closely with him this week and take him back to basics to restore his confidence.
“Lindelof is only 23 and will feel he has to justify his £30m transfer fee. Like Henrikh Mkhitaryan last season, Lindelof may not yet be ready for the Premier League. He should be given time to adapt and develop.”
With the home crowd in rapturous mood, the Yorkshire rain and wind swirling, and Huddersfield clattering into United at any possible moment, hellbent on winning this game through sheer brawn, Lindelof was in an alien universe.
He would have never experienced a game like this before in his career. That much is clear. He looked, above anything, incongruous.
And yet, he isn’t the first to experience this kind of baptism of fire. Patrice Evra, Nemanja Vidic and Laurent Blanc all experienced similar early starts and duly rose to the challenge.
Supporters will watch on closely to see whether Mourinho’s £31m man can do the same.
