Gary Neville, no doubt, knows more about being a right back, but, on the other hand, I dare say all of us on here have watched Kyle Walker play more often this season than Gary Neville has.
I mean, maybe he is sat at home watching every single game in the Premier League, witnessing every mistake made by every player, but I doubt it. It's hardly in keeping with the work ethic of most professional footballers.
As Moonlit says, two different pros frequently have differing opinions on players. I don't think you're entitled to condescendingly dismiss someone's argument just because you happen to have one professional footballer in your corner.
On the specific issue, as is on record, I rate Corluka very highly, for reasons mentioned before. He did have a period of bad form/injuries, and I can understand why Redknapp looked at other options and settled on Walker. I do, however, think Walker has been hugely overhyped, largely on account of that attribute that always seems to excite fans unduly - pace. As a personal preference, the thing that gets me excited as far as defenders go is their positioning and intelligence/reading of the game. Corluka is way ahead of Walker in both of those, in my opinion. In fact, Walker is at a remedial level at this point - regularly costing us goals with poor marking/positioning, and giving away an endless stream of freekicks in dangerous positions by diving in to challenges.
He's still young enough to eradicate that from his game, of course, but he's also shown sufficient tendency to duplicate errors that he may ultimately be relegated to the Glen Johnson, didn't-ever-really-progress-past-his-early-promise, category.
