Ilkay Gundogan's decision to join Barcelona can be considered a wise decision because he still hopes to appear in Europe with a big team. Barcelona is a good team in the history of football, so joining Barcelona must be something good in a few seasons before approaching retirement.
Yes, I thought so too. It is undeniable that the older a soccer player gets, the dimmer his career opportunities will be. And right now, if he does move to Barcelona, that's a very good thing too. Barcelona is a big club in La Liga and he is in the championship team this season, and of course he can still join the UCL again. With his current abilities, with Barcelona, it is hoped that they will have each other or provide benefits for both parties. Barcelona is getting stronger because of Gundogan's ability and quality, and conversely Gundogan has also got a big club with a relatively high fee.
