The transformation that has occurred at Manchester City over the past 12 years is undeniable.
Former captain Vincent Kompany summed it up perfectly during the All or Nothing Amazon documentary when he was sitting in the state-of-the-art training complex describing the conditions when he joined the club.
He told assembled schoolchildren of cubicles with broken doors and a gym with just one boxing glove.
Now, City have a purpose-built football academy and training ground, and have also extended the Etihad Stadium.
Then there are the trophies City have lifted, including four Premier Leagues.
Everything that makes City one of the top clubs in the world stems down to the investment from one man - Shekih Mansour bin Zayed Al Nahyan.
When Sheikh Mansour bought City in 2008, the club were a perennial mid-table side. Now, they have realistic sights on winning the Champions League.
Of course, City are not technically owned by Mansour outright. Instead, the City Football Group wholly own the club, of which Sheikh Mansour's Abu Dhabi United Group has 86.21% shares.
