Not really. There are a lot of trick moves to master, but most of them are for show. You can get deep into the game, but the learning curve is shallow.
FIFA 08 has completely revamped the series. They have slowed the game down and it is much more like real football. In fact it is for the first time more realistic than Pro Evo/Winning Eleven and I thought I would never say that.
I made this clip of some of some of the first goals I'd scored. You can see that the game looks quite real and the runs of the players off the ball make for some nice moves.

Have a look around Youtube and you'll get a reasonable idea of the footballing model, and to see goals that are a lot better than mine.
