Scholes is ahead for me, and it's because of the things that Neville pointed out - those little things that are hard to see. Carrick has some of the same abilities, that you run a match without anyone really noticing. Scholes was obviously a level or two above Carrick though. Scholes had an uncanny ability to dictate play in ways that Gerrard could only dream of. Gerrard still keeps trying to run past players even though everyone else can see he no longer has the pace to do so. Scholes never relied on the physical aspect of the game. His technique was far superior to the others; if he had been Spanish, he would be regarded as good as Xavi, at least. I've never seen anyone hit 40-50-60 yard crosses like Scholes - Gerrard isn't even close. There is way too much air in those passes comparatively. Scholes more or less shot them to the wingers with inch perfect precision. His short passing in around the midfield circle really was something to behold also as he was almost impossible to steal the ball from - until he had one of his brainfarts from time to time. (Gerrard and Lampard certainly have theirs too)
Gerrard vs Lampard is a bit of a toss up. I do think Gerrard is the superior player, but Lampard certainly contributes with his goals. You might say you'd like both in your team, but honestly, you wouldn't - they are the ones to compare, not Scholes with them. To still continue to play with Lampard and Gerrard in CM is starting to get a little tedious - it used to be funny, now not so much.
