The defensive midfielder comes in with a big reputation as a player with huge potential.
However, he did not always show his best qualities at Goodison Park, which he puts down to a style of play issue. Speaking to speaking to La Derniere Heure, as translated by Sport Witness, the 22-year-old stated:
"The European Championships have boosted my value.
"I'm convinced of that. My performance at the European Championship was in balance with the player I am and the qualities I have.
"At Everton we often played a completely different type of football. I was able to show all my qualities at the European Championships. I was enjoying myself on the pitch, I think it showed.
"I was very confident that the European Championships would accelerate my future. Mentally I was fully ready to give the best of myself and I think I did my job well."
