Speaking to ClaretandHugh exclusively, Redknapp paid tribute to the Canning Town-born Hammer and explained why no club had ever made a serious move for him.
Redknapp-managed Queens Park Rangers arrive at Upton Park on Sunday with Noble facing a fitness race on his shin/calf problem.
But the former Hammers boss was keen to pay tribute to a player for whom he says he has always had a great admiration.
He said: “Mark is a throwback to the days when club loyalty was everything and it’s really refreshing to see.
“People have often wondered and asked why no club has come in for such a good player but the answer is obvious, he’s a Hammer to his backbone.
“I believe at one time I was told there was some interest from Fulham but I just don’t see it happening.
“For me he’s a top player. I have a lot of admiration for him and his game. I can’t ever see him moving on.”
