A&O’s new US corporate finance partner Kevin Muzilla led a London-based team acting for the issuer, MU Finance.
Latham is understood to be advising the banking syndicate financing the deal. This includes Deutsche Bank, Goldman Sachs, JP Morgan, Merrill Lynch and RBS.
United, the current Premier League champions, this morning confirmed that it will seek to raise the money through senior secured notes, due in 2017.
A&O is the longstanding corporate adviser to the club, having acted for Malcolm Glazer when he bought the club in 2005, with relationship partner Andrew Ballheimer taking the lead.
High yield expert Muzilla joined A&O in October last year from Milbank Tweed Hadley & McCoy, where he had been partner since 2000.
