France coach Didier Deschamps is full of praise for Chelsea target Eliaquim Mangala.
Deschamps said: "He played the entire season at FC Porto, was champion, played in the Champions League. Had also played in Belgium. He is a defender with good physique and has a good left foot, allowing him to be effective in individual duels.
"Mangala will discover another level, he has potential and everything you need."
