Chelsea midfielder Enzo Fernandez is full of praise for teammate Joao Felix.

Both players arrived last month.

And Fernandez says he's been impressed by Portugal international Felix, who is on-loan from Atletico Madrid.

"Felix is a great player, just incredible," said Fernandez.

"He has an impressive set of qualities, which makes him a key figure for our team. I hope that in the summer Chelsea will do everything possible to keep him here."
