This is because inter Milan has refused to bring in younger players to strengthen their squad and this has impacted negatively on the and we saw that in the finals of the Euefa champions League finals were they were humiliated by PSG, inter Milan should start a rebuilding stage if they are to come back to competitive football challenging for titles.
The issues with most clubs in the championship and premier League is that, they want to achieve results with same old players, instead the clubs that didn't perform well last season needed to spend a lot of money to buy new players that will have positive impact on the club's performance for this season but they failed and now still struggling playing the same old pattern of football.
Not all of them, though, but most of them are affected with this same issue, which I don’t know their reasons for. Because no matter what, if you want to achieve success, you have to put in a big effort, which is one of the things many teams lack. It will be very hard for such a team to achieve great success with the same tactics and strategies they used in the previous season. You see, it will not be so easy for them to overcome their struggles.
Although most of the teams are starting to understand, and we are seeing changes, so it might change for them, maybe. But the Premier League and Champions League are competitive leagues, and without improvement, your performance will just get poorer instead of improving.
