Wow. Very interesting and a little strange.
Strong left winger, likes to score, very fast, defender's nightmare. However... why are Everton after him? He is a flare player that disappears if he plays within a system that does not feed him. At Olympiakos, they play through their wingers Abdoun/Mirallas/Fetfatzidis and have one player in the middle to mix things up, Fuster. This system gives lots of possession to the wingers especially Mirallas who everyone is instructed to pass to.
.....................Meigeri....................
Torosidis....Manolas..Pablo.......Holevas
............Ibagaza....Maniatis............
Abdoun.........Fuster.............Mirallas
................Djebbour............
Unless the system is similar in that it is geared to full attack and full pressing without the ball, players like Mirallas, Abdoun, Fetfatzidis.....these players will disappear during a game.
