I think that the people need more challanges to keep the intrest and be entertained in T11.
The achievements that developers created are a little bit fast to win, and I will suggest another type of achievements to unlok but, during a year.

Examples:
Unlock a special Jersey, Emblem or title, after win 3 Leagues/Cups or Cl's during a natural year, then a 2nd jersey after 5 and 10.

Or one can have the right to use a special jersey or so, after win a title or some amount of these...

I really hink that we need something of that.
