But in a tweet he insisted he had no idea what was on the paper when he held it:
Arsenal players have been trolling Spurs in several different ways this season, so it was conceivable that this was simply the latest.

Cazorla denies stoking the fire, and he wouldn't be the first sportsman to be caught out this way.
Luis Suarez, while he was deliberating over a new Liverpool deal, inadvertently signed a fan's piece of paper on which it was written that he'd commit to the Reds for another five years. It probably wasn't legally binding:
