Watching him on TV playing Queen's in 2005, and Wimbledon the same year.
I can't even remember much about Andy's matches at either tournament, apart from him going down like a sack of spuds at Queen's, and then cramping when two sets to love up on Nalbandian, but there was just something about the way he played. The shot-making, the ability to read the game, to drive an opponent a bit mental, was all there, right from the start.
Andy was this long string of raw talent. Someone else said it exactly right, a Brit who wanted to win - with all due respect it seemed almost unheard of! I've said it before, but to me, with all due respect, Andy was always more John McEnroe than Tim Henman in those early days. Andy had attitude, which is never a bad thing. He could also be fiery, which wasn't always helpful. However, what he also had was a deep and intense competitive spirit. He liked winning, hated losing. Makes sense to me!
I vividly recall watching Queen's in 2005 and telling people we had a player who was going to win grand slam championships. I was certain about it. I told people that his first would be the US Open, and then Wimbledon. I remember being laughed at, or smiled at indulgently. Well, who is laughing now?
