The former Manchester City man feels the Tottenham Hotspur striker must leave the north London club.
Marsh used the words 'mediocre' and 'second string' to describe the White Hart Lane outfit and has says he would love it if Manchester City signed the 22-year-old.
But Roberts feels Marsh is talking 'a lot of rubbish,' suggesting becoming a Spurs legend will mean more to the striker than a move away.

It's an interesting area for the future, of course, as Kane is clearly a Tottenham man at present.
Will the young forward's head ever be turned, though? It's a debate Marsh has opened up but it's clear Roberts, among many others, will strongly disagree.
One thing's for certain and that's Kane's importance to Spurs. And he may well now have extended that to England, too. After the 22-year-old's emergence from the substitutes' bench against Switzerland, the Three Lions were simply a different team.
Wayne Rooney looked more natural from a deeper position and Raheem Sterling, Alex Oxlade-Chamberlain and co finally had a natural spearhead to provide service to.
