Manchester City owner Sheikh Mansour has promised supporters there is much more to come following the 10th anniversary of his takeover, adamant they are still "only half way up our Everest".
City were in a dire financial state before Mansour purchased them in early September 2008, but since then their fortunes have changed dramatically.
Mansour, a member of Abu Dhabi's royal family, has reportedly invested more than £1.3 billion ($1.7bn) in City, developing state-of-the-art facilities at their home base and transforming them into one of Europe's elite.
In the 10 years of the Mansour era, City have won three League Cups, the FA Cup and a trio of Premier League titles, including last season's record-breaking success, but they are yet to claim that elusive maiden Champions League crown.
Therefore, Mansour feels City still have some way to go and lots more to win.
In an open letter to City fans, Mansour wrote: "So, what do the next ten years hold? I know you all remain ambitious and so do I.
"It feels that we are only half way up our Everest. There is much more to do and there is much more to win.
"That is why you will continue to see us strive to recruit the very best talent into this club and its sister organisations in all functions and at all levels.
"Khaldoon [Al Mubarak, City chairman] and I know that we will not get everything right all the time.
"As we continue on this journey I would ask you to please always bear with us and please be assured that, even when we stumble, we will try to remain true to our values and to make you proud of what we do and how we do it on your behalf."
