If you watch the video you can clearly see Carroll, Spearing adn Aquilani with Nintendo 3DS's. Adam and Kuyt probably have one too which is why they were all consulting. You can catch Ngog too with a DSi:XL... Liverpool players love Nintendo!!

Edit: How do you link videos?!
My 2 favourite things on Earth combined: Liverpool and Nintendo :D ... And yes I'm a bit hyper right now :P
