The league leaders have announced an eight-year sponsorship deal with the American insurance company which will see the facility named the Aon Training Complex
The agreement with the American insurance company, which starts in July, is thought to be worth around £15 million a season and will allow Aon to advise United on global expansion and offer data analysis and research.
Aon are currently also the club's main kit sponsor, but are set to be replaced by Chevrolet from the start of the 2014-15 season in a $559m [£364m] deal.
Aon's global chief marketing officer, Phil Clement told the BBC: "When we started the first partnership people didn't recognise our name," he said. "But by 2010 half the decision makers of major companies said they recognised our logo.
"We still want to drive our brand but we've hit the awareness goal. Now we want to use the relationship with Manchester United to better engage with our clients."
United were the first team to sell sponsorship rights to its training kit two years ago DHL - only to buy out the £40m deal in October, 2012, with the view to a more lucative deal elsewhere. Aon's eight-year deal is valued at around £120m.
