Maybe he reads foot.ie. After all, the site seems to be proliferated by "lose weight fast" advertisements lately.
lampard is an example of a player who upped his game after losing weight. I took over a minute off my 10k times last year just by losing 1kg. It all counts!
even while not at peak condition he was still a fit player, capable of putting in a hard shift over the 90 minutes. We don't doubt that. However, now he's lost weight, how much better can he get?
It's a simple fact that more weight requires more oxygen & energy to carry. Look at Bradley Wiggins in this year's TdF, and he was already in superb condition. He probably went too far and can't sustain his TdF weight without compromising his health, but it's still illustrative.

A simple analogy would be that your car would be less fuel efficient if the boot was full of suitcases.
