Chelsea hero Marcel Desailly has spoken about the quality of a rival defender this week.
Desailly, whose Chelsea take on Arsenal after the international break, spoke about Gunners stopper William Saliba.
Speaking to Gambling Zone, Desailly said: "I wouldn't say Saliba is the best in the world yet.
I believe that Dayot Upamecano and Virgil Van Dijk are above Saliba, even though Van Dijk has dropped a little bit.
"We do, however, need to give Saliba time. He only arrived two years ago and, back then, nobody knew his name.
He was never mentioned! Let's allow him to exercise and practice his craft at the highest level."
