The Swedish centre-back arrived at Old Trafford from Benfica during the summer transfer window, in a deal worth in excess of £30 million, but is yet to start a Premier League match.
Lindelof was given the nod to start against Real Madrid in the European Super Cup last month, but it seems his shaky display has played him out of contention, allowing Phil Jones and Eric Bailly to build-up a useful-looking partnership in his absence.
But Mourinho insists the 23-year-old will still come good.
Speaking in an interview with the Times, Mourinho explained: “Lindelof was the only one that I didn’t work with [before].
“But in Portugal I control. I control inside information.
“I know the qualities of the people, I know many things about social life, about private life, I know because even without working for that, the informations are arriving.”
Despite his absences domestically, Lindelof is expected to start Tuesday night’s Champions League tie against Basel – but what do you make of Mourinho’s comments?
And should fans expect the finished article when their club has paid more than £30 million?
