Chelsea captain Cesar Azpilicueta has heaped praise on the club’s January signing, Joao Felix.

Azpilicueta branded Felix as "unbelievable" in training, adding that the Portugal international is good.

According to him, he was "surprised" Atletico Madrid agreed to loan him to Chelsea.

When asked if Felix is a "special talent" ahead of Chelsea’s UEFA Champions League last-16 first leg clash at Borussia Dortmund on Wednesday night, Azpilicueta said at his pre-match press conference: “Yes, he is."

“I knew him from Atletico Madrid, when we played against them, and from watching their games in La Liga.”

He added, “I was quite surprised when he arrived because we know the quality he has." He is amazing in training, and in the last game against West Ham, he showed the way he can turn, create spaces, and play passes.

“In training, he has been unbelievable and honestly very good.”
