Our Aviva Premiership partner club Saracens have come up with a new competition with their main club sponsor Allianz. You have to guess how many rugby balls were Saracens players David Strettle, Mako Vunipola and Chris Wyles able to fit into the back of a Allianz-branded taxi.

If you get it right you "Win a pair of tickets to the Premiership Final at Twickenham on May 25 and a taxi full of rugby balls for your school or junior club team."

To enter see Competition Entry Page. You don't even need a Facebook account to enter.

The competition ends on at midday on 21 May 2013.

For about as much of a clue as possible, check out the video of the players filling the taxi - YouTube video.

Seeing how many they look to have fitted into the back I reckon there might even be enough for one ball per minis player ;-)
