Video: Diego Costa appears to throw celery at Chelsea fans during title parade

It's party time in west London.

Chelsea won their first league title in five years this season and have today paraded the Premier League crown through the streets of London in an open-top bus. Top scorer Diego Costa was among the players and in obvious party mood. And what better way to celebrate a successful season than by throwing celery sticks at the crowd.... Costa appeared to be doing just that today, flinging the vegetable at revealers, who were throwing the celery back at the Chelsea striker. Strange behaviour all together, they really know how to party in west London. https://twitter.com/FourFourTweet/status/602803459541364736
