for me he should have to answer questions about that. at first i thought he was maybe just doing a silly jumping thing, maybe trying to make sure he sees everything but when he waves his hands forward he is almost willing the ball over the line.
He had a bad call giving Spurs a penalty on a Bale dive that put them up 2-0. It could have been worse because it looked like he was going to give the Arsenal goalie a red card for the phantom foul but the linesman talked him out of it.
That's a definite guilty for me. Skipping for joy and 'ushering' the ball over the line shouldn't even be done by players let alone the 'impartial' ref. That said, I saw nothing in his actual decision making to suggest that he gave spurs any advantage.
