Spur of the moment
Frederic Kanoute
Guilt, is my guess. Doubtless Zidane fired them up at HT so Bale knew he was expected to fight for the ball. Having lost possession (which is where the guilt comes in) he needed to show he wasn't going to let his opponent get away easily, but he was never close to winning the ball back so frustration got the better of him.Very unlike him - he just kept trying to hack at the Las Palmas guy's shins for twenty-odd seconds until the ref gave a foul. No attempt to play the ball in that entire time, just kicks to his shins trying to bring him down. Then loses his head when the LP guy understandably shoves him in anger once the foul's been given.
Wonder what got him so worked up.
But as you say, so very unlike Bale. Can imagine though it's very difficult to stay grounded when you are surrounded by the kind of febrile atmosphere that must exist at the Bernabeu.
