"The problem is your European game is too slow and stilted" - Lula might have been saying.
So it's not every day that you tackle the president of Brazil dressed as a member of his national football team. Or at least, I don't. (Tackle in a very metaphorical sense, I should say.)
But when you want to attract Lula's attention in order to tell him that he should really go to Copenhagen in December to push for a strong climate deal, the legendary prowess of the Brazilians at football is an obvious avenue to go down.
