Is good to hear that both side have come to an agreement and the striker will have his peace of mind. Many of us never thought of him going back to Galatasaray even myself because the EPL teams are the ones looking likely to get him especially Chelsea in particular but it seems they ain't serious about him. If he had player for Napoli then whatever comes he shouldn't complain about it because they really hurt him when he was seriously showing how much he love the club.
Al-Hilal are never in the mood to give up on getting him and if care is not taken they could still be checking up on him like 2 to 3 years later to see if he's willing to join them. But I was thinking that he would have joined one of these Europe clubs maybe any of the power house that always shows up in the champions league but Galatasaray is not that consistent if you ask me, maybe he'll only struggle with the team to stop at the round of 16 or quarter finals...let's hope he continues showcasing his ability in the Turkish league.
