Manchester United defender Raphael Varane sustained a hamstring injury in the Champions League draw with Atalanta on Tuesday and will be out for around a month, the club said on Wednesday.
The 28-year-old France international started the match as part of United’s three-man central defence partnership, but had to be replaced in the opening half.
Varane only returned to the team for last weekend’s 3-0 victory over Tottenham Hotspur after overcoming a groin injury sustained on international duty last month.
