Oh, this? Just one of the world's greatest football teams in training ahead of the new season. Perfecting their shape, touch, sharpness and then smashing each other to pieces inside giant bubbles. That's how you win leagues, kids. Stick that in your coaching manual.

After a hard few days training at England's St George's Park base, the Barcelona staff treated the players to a little game of bubble football. You know... the game reserved for boozy stag dos, charity events and multiple Champions League winners. With the score being completely irrelevant, the players and staff flew into each other to see who could do the most damage and have actual fun, yeah, fun. Watch Lionel Messi go rolling across the Burton-Upon-Trent countryside in a giant bubble and try telling us that the fun in football is dead.

Some description

Now to start a petition for UEFA to demand that they must remain in these bubbles the next time Arsenal draw them in the Champions League last 16. Rumour has it Stoke City also play this game in training every day... without the bubbles.
