The Real Madrid defender has said that his international colleague will be "fine" to feature in the showdown
Raphael Varane is confident a niggling knee concern will not keep defensive partner Samuel Umtiti out of France's World Cup semi-final against Belgium.
Umtiti has carried the problem throughout the tournament and was rested for last week's 0-0 group stage draw with Denmark.
The 24-year-old returned for the last-16 win over Argentina and completed another 90 minutes in Friday's 2-0 defeat of Uruguay, despite showing signs of discomfort.
Varane, who scored the opener in the latter, believes the Barcelona man will be fit to help contain the likes of Romelu Lukaku in St Petersburg.
