Although there has been no official figure placed on the wide-ranging deal with Abu Dhabi-based Etihad Airlines that was announced on Friday, it has been suggested by one source the overall sum could eventually run into "hundreds of millions".
Cook knows the good work must continue if the Blues are to meet UEFA's financial fair play target, which allow them to lose just £39.7million over the next three years, hence the bold plans underlined on Friday. He said: "It is well documented where the major clubs sit with regard to their revenue lines, but we have tremendous opportunity here."
He added: "We have delivered, in the last three years, success through investment in our future.
"That future will reap commercial reward. Those targets and plans are laid out over the next five years.
"The ambition is to continue that growth and be able to compete with the largest clubs in the European market."
Manchester City Council appear happy with the Blues' progress, with leader Sir Richard Leese claiming it will pocket around £20million from the club over the next five years following an amendment to the long-term agreement to use the stadium.
"Earlier in the year, we formally agreed a new rental agreement for the stadium," said Leese.
"We did that in an open, transparent and accountable way.
"That gave us an increased income stream over the length of the rental agreement. We will invest that back into the community."
