I've lloked on youtube for it but to no avail, however my 2 favourite bits are both by the same guy.
I remember watching the opening game of the 1990 world cup and maradona was doing his warm up. He did a bit of keepy up on his shoulder, but the ball bounced about 10 feet up in the air, and he did this about 10 times.
The other bit was a story that Gary Lineker recounts about his first day in training at Barcelona. Apparently wee Diego just stood there and hoofed the ball 25-30 feet up in the air, repeatedly. Without moving, just straight up and straigt down. Once again he did this about 10 times, and then just trapped it on the ground and walked away.
The rest of the Barcelona players spend the rest of the day running after hoofed balls in the air trying to copy it, and the most anyone managed was 3 and that was with running after the ball.
