Who has the best starting 11? I play the same formation and find there's way more 'random' results when I play against someone with the same/similar formation. Normally the best starting 11 wins (obviously) but when I play against the same formation I quite often lose against worse teams or win against better teams (I won the CL final last season with quality 36-37 vs quality 44 with the same formation).

If he has the better team, I'd stick with it...
