I think Gallagher may fancy jumping ship out of Atletico simply because he went from star midfielder to random sub over the course of the season.
He's an all action player. Those claiming he wasnt "good" at Chelsea sound like they dont know what theyre talking about.
The Chelsea fanbase saw him as a fan on the pitch, all heart, never give up attitude. Yes he didnt have the stats he had at Palace where he played the Doucoure role, instead he had the stats of a box-to-box central midfielder.
If we had him then you know that it would be that infectious dogs of war attitude in the middle. Very Everton.
