Raphael Varane and Casemiro, according to Manchester United midfielder Fred, might be crucial for his team against Barcelona.
On Thursday, February 16, the opening leg of the two European powerhouses' UEFA Europa League playoff match will take place at the Spotify Camp Nou.
In this thrilling tie, both clubs will be down a number of players due to injuries and will rely on whatever experience is available.
In particular, Casemiro and Varane faced up against the Blaugrana frequently when playing for Real Madrid.
While the Frenchman worked on Los Blancos' books for ten years, the former spent eight years on them.
Fred thinks that on Thursday, Manchester United may benefit from the pair's previous encounters with Barcelona.
David de Gea, who spent his formative years at Atletico Madrid, may also contribute, in his opinion, according to him.
