One of the important members of Inter squad, Hakan Calhanoglu, is likely to leave the team this summer. Turkish teams have been strongly interested in him recently.
But there is a big issue on the other hand, his transfer fee.

Inter normally wants an amount like 30 million euros. Honestly it is too high considering he is 31 years old. They will be asked to decrease that price tag otherwise it is unlikely to see him leaving. When it comes to the reason why he could leave is that some in-team issues. I have heard there was a quarrel among the players during the Club World Cup. Otherwise Calhanoglu still liked to be a part of Inter. Let's see how this ends...
30m is way too much for Hakan. It makes more sense if Inter sells him in 20m - 25m range. They have also found Granit Xhaka as his replacement. The better they say yes for Fener's offer because of keeping Hakan much longer will only give them disadvantage as they may not able to recoup some money from him in the future.
I've heard he is also personally agreed to return back to the his home, and his father happy with it. The better they to let him leave.
I consider his age as my main concern. No club is keen to signing him when he's 32 years old ++.
