New Monaco signing Aleksandr Golovin's debut will have to wait after it was confirmed the Russia international has an ankle injury that could keep him out for the next month.
Golovin was one of the breakout stars of the 2018 World Cup and garnered him heavy interest from Chelsea throughout the summer.
But a move to the Blues did not materialise as Monaco came in with a late bid to secure a €30 million move from CSKA Moscow to the Ligue 1 side.
However, he did not feature in the Trophee des Champions last weekend when Paris Saint-Germain recorded a 4-0 victory over Monaco.
Monaco have now confirmed on their website that Golovin has a "sprained right ankle" that he sustained in training, with the player revealing the extent of the injury.
"I have an ankle injury, the operation is not required," Golovin told Sport-Express.
"The process of recovery will take about three-to-four weeks."
Monaco open their Ligue 1 campaign against Nantes on Saturday, hoping to improve upon their finish last season when they finished second but 13 points behind PSG.
