Manchester United survived a late VAR scare as Raphael Varane's second-half goal saw them edge past an impressive Wolves to get their Premier League campaign off to a winning start at Old Trafford.Varane headed home from close range with 14 minutes remaining to ensure an unconvincing display from Erik Ten Hag’s team ended in a 1-0 victory that was barely deserved.Indeed, it looked like Wolves might get the chance to equalise from the penalty spot at the death when goalkeeper Andre Onana appeared to clatter into Sasa Kalajdzic, but referee Simon Hooper waved away protests and VAR backed his decision.It felt harsh as few will have seen a performance like this coming from Wolves, whose plans for the season were thrown into disarray last week when boss Julen Lopetegui left just five days before kick-off, with Gary O’Neil coming in.O’Neil, who was sacked at Bournemouth after keeping them up last season, will have been thrilled at what he saw as his new side put in a slick counter-attacking display that had United on the run for the majority of the game.But it was old failings that came back to haunt them as they could not take any of their chances, with the electric Matheus Cunha hitting the post in the second half.United will know a display like this will not be good enough, but they at least got the job done to ensure they join Manchester City and Arsenal in taking maximum points in the opening weekend of the campaign.There was a small scale demonstration outside the ground before kick-off as United fans again chanted against the Glazers and the lengthy sale process of the club, which has been going on since November.However, planned protests against the possibility of Mason Greenwood being integrated back into the squad
