Chelsea fullback Malo Gusto says competition with captain Reece James will take his game to a new level.
The pair will battle for a place at right-back after the international break with both players now fully fit.
“We give each other a lot of advice, he tries to help me and I try to help him as best I can," the 20-year-old told RMC Sport.
“On the pitch, it's war, he knows it very well.
“We don't necessarily do each other any favours and simply the best player will play."
Gusto also said of senior teammate Thiago Silva, “He's one of the greatest defenders in the world.
“He's always on top and focused on what he's doing. Seeing that he's always giving it his all is something that's beautiful and inspires me a lot."
