Man City boss Pellegrini coy on Bony links
The Swansea City striker has been heavily linked with a move to the Etihad Stadium in recent days, with the player's agent claiming on Wednesday that a deal could be "a few days" away.
However, Pellegrini was not prepared to discuss the reported £30 million transfer at a news conference on Friday, insisting he would wait until a deal had been completed.
"I will answer this question when I know more about that because I don't talk about rumours," he said.
"We are going to replace Alvaro Negredo because it was the decision that we took in the moment we sold him.
"We decided to see in December if we needed another striker.
"We need another striker, so we are going to find which is the best player to bring in."
While Bony looks set to arrive at City, James Milner has been linked with a move away from the Premier League champions with his contract due to expire at the end of the season.
Liverpool are thought to be keen on the England midfielder, but Pellegrini is reluctant to allow him to leave.
"For the moment there is no news," he added.
"I think James wants to stay and we want James here, so I hope he will sign [a new deal]."
