Chelsea goalkeeper Edouard Mendy joined the club from Rennes with little reputation, as the Blues spent £22m to sign up the Senegal international last summer.
Mendy is in his second season at the club, and the 28-year-old has impressed massively for Chelsea.
After another fine performance in the 4-0 victory over Juventus, Mendy has now earned praise from former teammate Willy Caballero.
Caballero has hailed the Chelsea goalkeeper as the best in the world and further revealed that his ex teammate keeps improving.
Speaking to BBC Radio 5 Live, as quoted by Metro, Caballero said: “I believe strongly that Ed Mendy is the best goalkeeper [in the world] – last year and at the moment this year he is the best.
“As he arrived last season in training I saw an amazingly talented goalkeeper in terms of power, in terms of speed – he is so fast when diving.
“He has very long arms and everyone wants that as a goalkeeper. He is showing in every single game that he is calm and he is improving with his feet, he is playing very well in the build-up.
“He is winning points for Chelsea – not just last season but this season too. He is enjoying performing at this level and keeping clean sheets.”
