Liverpool defender Kolo Toure says Wilfried Bony must toughen up to make it at Manchester City.
Toure has warned the departing Swansea City striker he will need a tougher mentality to survive at the Etihad.
Former City star Toure said: "This is another step for Wilfried. He needs now to be mentally really strong because there are tough players there and the competition is tough.
"For him, it's the next level. When you play for City you have a chance to be champions, which is amazing for him."
