Giggs at his peak was a fairly unique exponent of the craft. Would not put him up there with the absolute ATG's but his ability to keep the ball close at high speed while selling body feints and changing direction was/is very hard to replicate. A lot of speedy wingers rely on kick and rush, and while Giggs did that at times in his youth it was that ability to run directly defenders at high speed with the ball glued to his feet that really defined him, made it very difficult to nail him with a hard tackle. Never gave the opportunity for the defender to line him up, the last thing they wanted to do was to commit, he would just shift the ball and go.
Still had that ability into his final years, remember a disallowed goal in his final year when he picked the ball up in the middle, spun, evaded 3 lunging tackles through body feints and played Kagawa through on the right, offside but he was near 40 at the time and left 3/4 players on the ground, so natural to him.
