Raphael Varane was signed during the summer, in a £40m deal from Real Madrid.
Injuries have prevented the France international from fully displaying his abilities at Manchester United.
Just five weeks into the start of his Manchester United career, Varane suffered a groin injury.
After missing two weeks of football, Varane was withdrawn midway through the first half on his return from the groin injury, as he suffered a hamstring injury that ruled him out for another six weeks.
Manchester United boss Ralf Rangnick has suggested that Varane wasn’t properly handled by the former boss, but the Frenchman seems to be fitter under his watch.
Asked about his options in defence ahead of the Champions League tie with Atletico Madrid, Rangnick said: “When Victor [Lindelöf] came on [vs Tottenham], he played well.
“As I said, it’s good to have Raphaël [Varane] fully fit again. We looked after him and he looked after himself, not playing too early again. Now he seems to be fit on a regular basis
“He’s [Varane] very important but with Victor Lindelöf we have also won quite a few games and played well and had a few clean sheets.
“Right now, we have top players in the centre of defence and it will not be so easy for me to take that decision for tomorrow.”
