Wilfried Bony said everyone at Manchester City wants to keep the "legend" Yaya Toure.
However, Toure's agent Dimitri Seluk has accused the club of making the midfielder a scapegoat and said last week that he was 90 percent certain to leave the Etihad Stadium this summer.
Inter Milan manager Roberto Mancini wants to sign Toure, but striker Bony, who is also an Ivory Coast teammate of the former Barcelona player, hopes he remains with City.
"We hope he stays, he's a big player here and we know everything he is doing for the club," Bony said. "Look at everything he has done over the years, what an important player he has been."
Toure has won two Premier League titles with City as well as the FA Cup and the Capital One Cup, scoring in both final victories.
"You can see his qualities, I don't need to tell you about it," Bony said. "He knows what he can do, everybody knows.
"For sure everyone wants to keep him here. He's a legend for this club for sure, he always will be."
Toure helped persuade Bony to join City when the striker made his £25 million move from Swansea in January and now the forward is trying to return the compliment by telling him not to leave.
"He knows what I think," Bony said. "He brought me here so he needs to stay. He told me this is a big club, how we were the champions. He told me it was a club that always fights and I am always a fighter so I liked that. He told me about the pressure, everything."
Toure has failed to replicate his form from last season in the current campaign. While he excelled before going to the African Cup of Nations, where he captained Ivory Coast to victory, he was less impressive on his return.
"It's been difficult for him," Bony added. "You have to remember it's been three years where there's been big tournaments: the World Cup, the African Cup.
"You need to play a lot of matches, you are playing in high temperatures, it's not easy. Injuries can also occur in that time, the pressure and expectations are high."
