Agree with this, less is more absolutely when it comes to the big games, otherwise by definition they aren't big games?
Bring it back to straight knockout over 2 legs, yeah obviously let the bigger teams in at a later round, but how good would it to see Real Madrid randomly dumped out by Valarenga or Man City by Grasshoppers who then go on a mad run to the final?! would love that personally. Realistically 9 times out of 10 the team you expect to win it will win it still, but thats got to be better and more exciting than this massive league format?
