Nowadays Right footed players play left wing and vice versa so that they can turn around and shoot rather than just crossing. That's why wingers nowadays score comparatively more goals than before..... I have had 2 AMLs who were right footed. 1st was Santi Cazorla(I bought him with that name). He was a beast, top scorer one season and 2nd highest scorer the next season. Now I have Zelenka who is also right footed and he is doing good so far
I don't think the game is programmed so well to make a difference with the players leg. Although I have seen that either footed players are the best at Free Kicks... Or it may be a mere coincidence
