Okay
Well there are advantages actually, sometimes you're being jostled but you manage to keep the ball and you can clearly see the referee raise his arms.
But nothing comparable to what we used to have back in PES4/5/6 as these occasions are not frequent enough and unfortunately I haven't seen any after clumsy sliding tackles, the most frustrating for me being during offsides..
As you may know in PES, referee strictness depends on referees so hopefully it'll be different in the full game.
