From my little knowledge, Minal should have extended Edin Dzeko's contract. Edin Dzeko is not a young player but he is an experienced complete player. Edin Dzeko has a lot of reputation as a professional player. Edin Dzeko was a good Inter Milan striker from what I saw. I think Minal's compromise with Edin Dzeko was probably the right thing to do. Dzeko wants to make a tough history in football in the end
I think they wanted to just rebuild, because getting the same old players to give them some talent could be good but it is not sustainable. If you buy a player that is 23-25 years old, you can do it for maybe 10 years, but at 37 years old Dzeko could be good for another season maybe, but it is not sustainable, you need to start thinking about the future as well. This is why I understand them not getting him back.
Plus, Inter, Milan, Juventus, Napol, and even Roma will have a chance to fight for the top spot next season. Probably not Roma, but all the others needs to build a team that could rival everyone and without that I do not think that it would be a smart decision, it would be much smarter to keep getting better results with younger players so you can have a better future in the league.
I believe Milan did the right thing. They should definitely get younger players on the team. I don’t think they should get rid of all the old players. Experience is also needed. But they definitely need young players to boost their performance for sure. The older generation is going to have a tough time keeping up against the young and fast players. If they can manage a good balance between the young and experienced generation, they will actually be able to do very well. I think this was the right decision taken by them about Eden Dzeko.
