Imagine footballers in the form of water (and why not? It's the one element that flows through our daily lives) and what do you see? Kenny Dalglish as a river, perhaps, a majestic, teeming river, like the Rhine, sweeping past the Lorelei; Eric Cantona as a lake, sparkling like a million diamonds when the sun dances upon the waves but also reflecting the darker moods of a troubled sky. Denis Law was a waterfall, Jimmy Greaves a geyser. Among current players Paul Scholes may be a secret spring. Emile 'where's the goal?' Heskey, alas, is no more than a puddle.
