Of course he can be but his age is too much for the Turkish league.I can't think that a 37 year old player can get much time in the Turkish league because the Turkish league is a very tough league and if he gets injured he has a chance to stay away from the pitch for 2-3 months.Other leagues don't have a tough game but not in the Turkish league.I know that he played for Inter and Manchester City in his time but I think his age is a bit too much for the league.Still, he might have the potential to play for 1 year.If a contract is made according to him, this seems to be no problem for the team and the fans.
Ryan Kent is coming to Fenerbahce so while they lost one striker and their manager, they gained a winger that is insanely fast, that dude is known for being able to run as fast as anyone you have seen and do that for 90 minutes, there is a reason why his nickname was "the secretariat" when he was younger (this was in 2019 if I remember correctly) so it is a good start.
If they get Dzeko that would mean they would have a proper striker, sure he is old but that would help them for at least one season and then they can look further next season, it is important to at least cover this year first. Those two alone are enough with a good manager, they could keep rest of the same team from current season and just add in Kent and Dzeko and a manager and do it all again.
I also think that Ryan Kent could be a good signing, but you have to ask who wanted this transfer to happen, the new manager or the president?
Of course dzeko is a very good striker in terms of finishing, but I can't be the only one who thinks that he will have a lot of injuries. Turkish league is a tough league compared to other leagues and it is a league that can have more injuries, especially for older players.
I think they will get a better result when they buy a striker and an extra winger.
