It was on Ref Watch on Sky Sports earlier (scroll down link for the video). In the video i don't think White actually manages to undo the glove because the Spurs keeper has his sleeves pulled down over the wrist of the glove, so clearly something had happened previously and the keeper was wise...
So Ben White joins Billy Sharp and Bernd Leno in having their careers ended at the Amex by brutal thuggery from Brighton players. I think we should dedicate a bit of the memorial garden in honour of their careers.
