I would try to score with my goalkeeper on world class since I've dribbled past everyone with my center mid from the midline and scored, but since most goakeepers have like 1-3 in shooting (kahn has 3), even when u dribble past everyone and the opponent keeper comes out and u press shoot ur guys shoots it right outside of the goal. once he kicked it sideways and made it a throw in =p. So yeah, I have the dribbling skills, but it takes ages just to get that goal.
For those who can't score on PC corners:
It might be possible. I'm not sure, I don't feel like replaying games over and over again just to get how to do it, but if you do, try pressing the s button for a while and when u get the guy to whom the ball is coming use a w in the direction of a goal. I succeeded with my player trying to head it, but never actually scored.
Or, what you can do is, low pass to the guy nearest ur corner, then run around for 1-2 secs for the pathway to midbox to clear and pass to ur player who's standing right in front of the goal and then quickly press d before the dude gets the ball. u won't have much power on it, but it's usually enough from that distance and the goalie doesn't do **** to take it off of you, even in world class. This is very hard to pull off tho.
OR, what you can do is, low pass to the nearest dude and then after like 1 sec pass back to the corner-kicker (beware, sometimes ur dumass players pass it outside of the field) and do a cross. I never scored that way, but I suck at crosses anyway.
Defending from corners:
Don't touch anything, but keep ur hands on the header/keeper charge button. If the ball is coming outside of the box (rare thing, but it does), try to head the ball out, usually works, if not, your goalkeeper should be able to get it, most of the time. If the ball is coming into the box, don't touch anything. If the opponent heads the ball, your keeper will save it. If the opponent heads to your def, just stand there until the mess clears up and then continue on with your game. If he heads it to his own player, press w instantly. It never failed me when I did. It takes some time for the player to trap the ball, then turn, and shoot, and if you do it right in time the goalkeeper will get it. That's like the most fun part of the game, cause it's always so damn close.
Scoring:
I dunno, I never EVER scored on crosses, I dunno **** about em. All I score with is breakaways. And since I beat the game on world class with like the worst team ever, I'm not that bad at breakaways.
First of all, don't use the freestyle button too much. It's good, but especially if your team sucks, when you use it, your player will never gain the stamina back. On a breakaway, usually 1-2 presses of the shiht button is enough. Of course, when you get the ball and the def is right in front of you, all you have to do is turn around and sprint like mad until u get into the box and then jod and shoot when the goalkeeper comes out. Sometimes tho, you have enough time to dribble past the opponent without using the shift button. It's easy enough to lose them. Let the opponent start pushing you, trying to tackle. Then, quickly, turn the exact opposite way (I use down and then up the field), the guy will fall, then you just use regular e-sprint in the direction of the goal and shoot. That's if you're close enough to the box. If you're not, I reccommend a couple of shift-sprints.
If you're more of a dribbling kind of gy, use your mids. The advantage to breaking away with a mid is that even on world class, you can dribble past the opponent defs without being touched at all - they're still holding down ur forwards. What I do is I run around the field in diagonals, down and up. I guy starts shoulder-barging me, I change direction and go on my diagonal again. after a while, I'm close enough to the box and then I just sprint right between the two defs, who r just standing there (you have to be right between them, they WILL tackle you if you're withing their tackle area), jog slowly into the box and slam the ball into the net.
With that, I got hat-tricks for all my non-defenders over like 4 games. Usually 2-3 hattricks a game.
