Former Manchester City star Rodney Marsh has urged Ross Barkley to make the move to the Etihad.Everton midfielder Barkley is a big money target for City in 2015.
"I would advise Ross Barkley to move to Manchester City in a heartbeat," Marsh told talkSPORT.
"He has the opportunity to become one of the greatest British players we've ever seen.
"He's the sort of player who can move to Manchester City and, unlike others, can get into the first-team as a youngster, dominate and become a truly great footballer.
"I would advise anyone at the moment who has the chance of becoming a top player to go to City, it's a wonderful club now. They've got everything in their favour, from their training conditions to being able to play around great players.
"This morning I spoke with someone who has seen every game Ross Barkley has played, even for Everton's youth team. He told me this kid loves his football, he trains harder than anybody, he stays behind after training and is a wonderful young man as well, and they truly believe he will go on to become a world star.
"Another player Everton let go as a youngster, Wayne Rooney, became the biggest thing in British football when he moved to Manchester United. I put Barkley in the same category."
