How it can be?
I became an 10 lvl, in my league there are different teams 11 lvl.
You are playing a level higher than you should.
Its not so bad, the scout list should be much better than usual, showing 7* players, and next season you will still be playing at level 11, so your players won't 'lose' a star.
I don't claim to be a Top Eleven expert but, if anyone would like advice, please don't hesitate to contact me through 'private messaging', I try to reply as soon as possible.
