Is it me or should Ibrahimovic's goal vs. Tottenham been disallowed?

He was holding him but come on, if someone is trying to get the ball away from you in the box, are you going to let them push you? Ibrahimovic is bigger and stronger than Dawson, that goal was spectacular, let alone 10x better than Crouch's goal. I see people holding each other all the time in the box, but it seemed like that goal should have been allowed, he was just fighting for the ball. But congrats to Spurs for counter attacking and taking their chances (without Bale too).
