A very good player, still only 24. I think he would be an excellent signing for the right price, perfect as the 10 behind Calvert Lewin.
When you have a midfield player, able to score a goal every 3 games for three seasons running. That's special. That is a player you build a team around.
He has had a difficult 18 months with injuries and Mourinho doesn't really play a system that suits him and has no interest in accommodating him.
If he had Allan and another holding player behind him, maybe even Doucoure, this team would carry a much greater threat.
If he is available, he is exactly the type of player Everton should target. A player who has lost their way but has shown they can play well at the highest level.
