Regarding the defending side of the game I agree with VCLMPX (dude you need a new username

)
I understand that in its current state it is a little over simplified and players can pressure non stop for 90mins without any fatigue involved which is just wrong. Barcelona, Liverpool, Dortmund Real Madrid, no team on earth can't do it for more than 20mins without taking a breather, nevermind a full 90
Also every player should not be able to defend like Verratti it must be related to the following stats
- aggression
- Stamina
- defensive prowess and
- box to box card
Having Ozil or Di Maria playing as defensive midfielders who are going to hassle you all game is not realistic and far too easy to pull off on PES
On curdstars point adding more buttons or inputs is going to hamper the enjoyment. I know exactly what he means about Fifas over complicated system. It's a mess and makes the games defensive game look wrong when in fact it might be pretty good just hidden under over complicated mechanics.
I imagine the only solution would be to only allow secondary press with the players that have the above trait or balance of stats that allow them to pull back and defend. In this way Ozil will not defend regardless of what buttons you press because it is not in his character to do so (I can imagine how this is realistic already) ... Now this opens an interesting thought. If you remember the old pes arrow system that you setup to dictate which way the players will cover the pitch, people hate that this was removed. I personally think it's the right thing. If you want overlapping fullbacks play with a team that have them or in the case of Master league buy the right players. If you now start messing with player traits and stopping them from defending because it's not in their nature, imagine the consequence from the fans who are already divided about the lack of arrows.
Personally I feel gegenpress and tiki taki must not be a universal ability. It can't work for every team because you don't have the players to pull it off.
Similar to trying to force Barcelona to play target man football. None of their strikers have the ability. Should the game allow it there must be consequence to it, which for target man might be right but I feel gegenpress and a few other game styles need to be revisited. You can't have a universal system that works regardless or the teams you use.
