Btt.: If you don't have a high budget, buying older players at the start of next season is a good tip. Personally I would not sign >30, but between 27-29 years old 5* as a low budget player. The reason is that these players still have a small development and you can field some of them also in the next season. Background: Try to manage to go into a new season with a working starting 11, since on day 1 and 2 you have cup matches, but at the first day of the new season the transfer market will be hell. Everyone has fresh money and the big token spenders show what they have. Avoid bidding wars there.
