Jim Ratcliffe accepts Manchester United have a lot to learn from their "noisy neighbours" Manchester City and Liverpool but is determined to "knock both of them off their perch" within three years as he set out his vision to rebuild the Red Devils.
Ratcliffe, 71, is now co-owner of the club he has supported since the age of six after completing the purchase of a 27.7 per cent stake which delegates control of football operations to his company Ineos.
He set out his ambition to challenge City and Liverpool for domestic and European silverware but called on United fans to be patient, insisting it will take two or three seasons at least for Ineos to get the club to where he wants them to be.
In the longer term, he is looking to work with the public sector on either building a new £2billion stadium to regenerate the area around the Old Trafford, which he envisages hosting England games and FA Cup finals, or redevelop the existing site at a cost of £1billion.
"We have a lot to learn from our noisy neighbour and the other neighbour (Liverpool). They are the enemy at the end of the day," Ratcliffe said.
"There is nothing I would like better than to knock both of them off their perch. Equally, we are the three great northern clubs who are very close to one another.
"They have been in a good place for a while and there are things we can learn from both of them. They have sensible organisations, great people within the organisations, a good, driven and elite environment that they work in.
"I am very respectful of them but they are still the enemy."
Asked about the timeframe to make United truly competitive, Ratcliffe added: "It's not a light switch. It’s not an overnight change – it’s going to take two or three seasons.

"You have to ask the fans for some patience. I know the world these days likes instant gratification but that’s not the case with football really.
"It’s not a 10-year plan. The fans would run out of patience if it was a 10-year plan. But it’s certainly a three-year plan to get there."
Ratcliffe also vowed to build the right structure around manager Erik Ten Hag and said was wrong that successive managers had carried the can for a decade of failure at Old Trafford
He said it would be "inappropriate" for him to pass comment on Erik Ten Hag's record but felt he and his predecessors were not working in the best possible structure.
"If you look at the 11 years that have gone since (former chief executive) David Gill and Sir Alex have stepped down, there have been a whole series of coaches, some of which were very good," Ratcliffe said.
"And none of them were successful, or survived for very long. And you can’t blame all the coaches.
"The only conclusion you can draw is that the environment in which they were working, didn’t work.
"And Erik has been in that environment. I’m talking about the organisation, the people in the structure, and the atmosphere in the club. We have to do that bit.
"So I’m not really focused on the coach. I’m focused on getting that bit (the structure) right. And it’s not for me to judge that anyway – I’m not a football professional."
