you basically hold the lef trigger in, and your nba player will do what they call "face up" defense, basically you get on them like white on rice..
Presumably you mean in a face-to-face confrontation, really close but without actually touching each other?
Something along those lines is needed in Euro08, although perhpas not nose to nose in terms of how close the players get. You simply cannot get in close enough from face-on to any cpu player in order to be able to tackle. They all just skip away with a beautiful bit of skill that, in reality, Ronaldo would be proud of and wouldn't pull off every time.
It's clearly scripted that they perform this skill as soon as you move the LAS to move in. The script is such that the cpu guy gets a boost of speed and skill, skips away with a neat animation, then the program moves your guy in after this litte animation has played out and the cpu player has long gone.
The real problem is that every single cpu player has this exact same ability. In fact, it seems to me like the minor nations' players are even better at it. I think EA's tactic with these minor nations to try and make them hard to beat is that they play a 10 man defence which is hard to break down (which is fine) but when they get possession, they can keep it for ages without avctually threatening your goal. I think I've only ever conceded 2 or 3 goals in total to any of these teams, and they all been when my defence has split like the red sea to let their sole stiker run straight through.
EA haven't programmed these teams to be particularly good at scoring or even creating chances, but have made them far too good at passing and general possession play in order to create some additional degree of difficulty than just 10 man defence. Problem is, a lot of us think it sucks in terms of realism and gameplay.
These guys should be weak in possesion, easily panicked into early and misplaced passes, more easily jostled off the ball, not stroking it around with consumate ease and dancing around every tackle.
