Sheikh Mansour bin Zayed Al Nahyan, whose takeover will be completed on Tuesday, has insisted he will not make unreasonable demands on City's manager.
The fabulously wealthy member of the royal family of Abu Dhabi will have a hands-off role, however, and has appointed his trusted ally Khaldoon Al Mubarak, who was at Eastlands on Sunday, as City's new chairman.
Al Mubarak watched as a Robinho-inspired City beat Portsmouth 6-0 - and afterwards Hughes said: "I have been very impressed with what he has said and the plans they have for the club.
"They have an understanding of what needs to be done. It's not going to happen overnight. They are very realistic in that respect - they are going to build the club and make sure that success is sustainable by investing in the team, in quality staff, in facilities and resources.
"If you look sat the way they do business historically they do it in the correct way. They know continuity enables you to sustain success, and that's what they want - the right people in the right places - and they will give us the resources to be successful."
Al Mubarak, 32, is American-educated and the man who negotiated a Formula One grand prix to be held in the United Arab Emirates from 2009 - and for FIFA Club World Cup to be held in 2009 and 2010.
Sheikh Mansour, who replaces Thaksin Shinawatra as owner, made it clear he has bought City as a private venture rather than as one of the Abu Dhabi United Group's investments.
In an open letter to supporters, Sheikh Mansour said: "Like you, we are excited about the future of the club, and we hope the securing of Robinho as a Manchester City player during the transfer window is seen as a signal of our very real intent. It has been an exciting two weeks for all of us.
"My intention is that Manchester City has the very best people at its disposal, both on and off the field. For that reason, I have asked my friend Khaldoon Al Mubarak to take on the position of chairman of the club. My request to him has been to put together a board and executive team that is worthy of the heritage and potential of Manchester City."
