West Ham boss David Moyes has consistently rejected the suggestion they would sanction an exit for his captain. The Scot has even slapped a £150million price-tag on Rice's head amid increased attention from the likes of Manchester United and Chelsea.
"Declan Rice is doing a fantastic season. Let's be honest about it because I really like him, I really respect him as a player. I've been seeing him growing since (Manuel) Pellegrini was the head coach of West Ham," Toure told Stadium Astro.
"He's doing fantastically well. Maybe one more season but I think he should go to the first big club, one more step, Champions League team for example. There he's going to improve and there he's going to be top.
"With respect to West Ham, they're doing fantastically well. David Moyes as a coach I know him, I respect him and with him Declan Rice can still progress, but if he wants to get on top of it, I think he should go to a Champions League team where he can make more impact."
