The 65-year-old former academy director left West Ham on Wednesday following a 43-year stay with the East London club.
Carr, responsible for producing the likes of Frank Lampard, Rio Ferdinand, Joe Cole, Michael Carrick and Glen Johnson, had been a club ambassador with the Irons in recent years, but was told that the job was no longer full time.
Of course, Noble will have also worked with Carr after coming through West Ham's academy, and the 29-year-old midfielder admits he was shocked to see the Hammers part ways with such a "great servant" to the club.
"I first saw it in the papers," he told the Daily Mail, via The Standard. "It was a shock to me.
"I don’t know what’s gone on in the background, I’ve been in Austria for two weeks solid [on a training camp], but what I can say is I know Tony very well.
"He’s a fantastic man, a great servant to the club. As we all know, the players he’s brought through in the last 20, 25 years have been phenomenal."
The Standard suggested on Wednesday that Carr had only been offered the minimum £14,000 redundancy payment in a claim which has angered West Ham fans online.
Carr's disappointment might be exacerbated by the fact that West Ham are moving to the Olympic Stadium this season. It is a very exciting time for the club but it does not seem as if Carr will play a role in the Irons' future any longer.
