Only the top 14 players in your roster is counted for your next seasons CUP draw. To get a good CUP draw your team must be weak. To win the League and CL your team must be strong. So winning the treble is a delicate balancing act, like walking on a tight rope, something I have yet to achieve. I have be weakening my team for 2 seasons not like Becks but by others methods, but remain strong enough to be able to win the league and CL.

If you head down a path of blindly power building your team, you may be down a dark path of no return.
