West Ham United's principal sponsor Alpari, have called upon a member of our first-team squad to take part in their keepy uppy challenge!
Step forward England under-19 right-back Leo Chambers, who was given one tennis ball and 30 seconds on the clock to complete as many kick-ups as possible…all you need to do is guess how many he managed before the time ran out?
All correct guesses will be entered into the Alpari prize draw for one of five footballs signed by West Ham United players.*
Check out the teaser video on the Alpari West Ham United microsite.
The competition closes at 12noon on Monday, 20 January 2014 (UK time).
