I'm not sure if you've done situational training yet but you should, still I'll discuss a few important moves. To do the ever useful sidestep, just hit r2 and 90 degrees away from whichever direction you're going at the same time. So if you're going left, hit up and r2, then it helps to hit diagonal/left (forward) again quickly to do a nifty little dodgy move and keep going forward (imo it's easiest to learn this on the d-pad b/c of the 90 degree requirement). This is a very useful move against the comp., but in WE no move works in all situations, you need different moves for different situations so keep that in mind. Also, much of the time, slight directional changes will accomplish more than any move, so play with those as well. To do a normal fake shot hit shoot then pass, except you need to hit pass literally a split second after shoot- I just roll my finger over the two buttons quickly. There are also double and triple fakes for when you get a little better that are pretty cool. Take a look at that list, get out on the practice field and let me know if you have any trouble with them (some are a bit tricky at first) and I'll try to help. Also it's key to remember many moves you don't need to use often. Like I said, a lot can be done without any moves at all, but at certain times they are very, very useful and you will get a hang of when these times are the more you play.
