Liverpool goalkeeper Pepe Reina showed off his reaction skills when he took the 'Batak challenge' on a new training machine.
The challenge is similar to a game of whack-a-mole, finding the right number to hit when it flashes up on the machine and getting the most in 30 seconds.
However, it didn't start out great for the 'keeper, who seemed a bit taken aback by the way the machine worked.
"That's not light enough," Reina said. "It has to be brighter!"
But the shot-stopper got the hang of it soon enough, and by his third attempt managed a much more credible 21.
