Trimboli told the Mail: "Manchester City understood the value of the player. They had a lot of other players who they thought at the time were more ready than Cole to be playing. They knew that potentially his future value was going to be high. Given the amount of football Cole had played, it was still a high number. There were people at Chelsea who had previously worked at Manchester City so they knew what they were buying. Credit to Chelsea because they were the ones who put the money on the table. Twelve months after that, that £40m looks like money very well spent."
