Tony Book, Ian Brightwell.
To have seen Tony Book and properly understood his significance to City I'd need to be at least 60.
And no disrespect to Ian Brightwell, but do you really think he's better than a player who has won 6x Premier League titles, a European Cup, 2x FA Cups, 4x League Cups, 2x Super Cups/World Club Cups, and is a 4x Premier League TOTY winner?
Not to mention the 93 England caps he has, the 2x Euros runners-up medals, the 2x European Cup Team of the Tournament awards, and the fact that some of the greatest wingers to ever play to the game have all had nightmares about him, knowing he's one of the most feared RBs in Europe?
Even still, if Book and Brightwell, and, for the sake of this debate, Pablo Zabaleta, were all better than him, that would still make Walker the fourth best RB City have ever had in our 130-year history. He's won more trophies for City than any RB we've had before and has consistently been one of the best RBs in the world for a decade.
Brightwell, good and loyal as he no doubt was for City, played a solid chunk of his football in the second tier and below. His biggest achievement at international level was a small handful of games for England's U21s team. He was also relegated with City twice in 1987 and then again in 1996.
Whichever way you slice it, Walker has been unbelievable for City. Well worth what we paid and more. He's been a big, big part of the greatest City side that's ever had and Pep Guardiola, the greatest football mind of his generation, played him week in week out for years. He deserves to be spoken about better than he is being.
