Cook revealed to City's website: "We've been to Milan four times and the delegation yesterday involved three lawyers that represent the legal counsel for Manchester City football club.
"It also involved a board member who had flown half way around the world from Abu Dhabi, myself and one other senior executive.
"We were confined to a room, with no food or drink, and we asked some questions of the football club and more importantly we asked some questions of the representatives of the player and they simple could not answer the questions.
"What they wanted to talk about was; 'how much are you going to pay him?' We chose not to get into that and we didn't make an offer to the player.
"Is he a great footballer? Yes. Does he represent all the values you would want to have as an ambassador of the sport global and were we looking for the opportunity to joint venture in areas that would take this club on to a different platform? Yes, but unfortunately the landscape changed and his representatives wanted to talk about how much we were going to pay him.
"Money was certainly the motive yesterday."
