Just seen the Eduardo incident and it is most definately a dive, although I must say diving is so prevalent in modern football that it only really bothers me when it goes against a team I have a vested interest in. Perhaps it's time to stop moaning at the players and start moaning at the authorities who do **** all to deter them from such behaviour. Fair enough they shouldn't do it in the first place, but it's so widespread now that hoping they will stop doing it purely on the basis of good sportsmanship just isn't going to happen.
If you want to see that it's a dive then don't bother focussing on whether the keeper takes his right leg, it's his left leg that gives it away here. That should be his standing leg, but once he's got the touch on the ball he doesn't even attempt to stand his leg or continue his stride, at all. This alone makes it clear that once he's nicked the ball his only intention is to go down.
