Manchester City chief Garry Cook insists their £400 million Etihad sponsorship complies with UEFA's Fair Play laws.
City have previously said the speculated figures concerning the Etihad deal are "not accurate".
City have also underlined the importance of the agreement to the Etihad Campus project, which will feature a new 80-acre state-of-the-art training complex near to the Etihad Stadium.
The facility will also include an academy for 400 players, 16 football pitches, injury rehabilitation units, a 7,000-capacity stadium and staff offices.
City chief executive Garry Cook told the BBC: "The Etihad Campus, which constitutes some 210 acres is unique in its breadth, depth and length of term.
"It involves the tradition, which is shirt sponsorship, the naming rights of the stadium, but what we haven't seen in football is a campus, creating a place to be, to work.
"We've got a great relationship with Etihad. It's a long-term programme and they are equally very excited by it."
