Ratcliffe was greeted by United chief executive Richard Arnold on Friday morning and will get a closer look at the club before submitting a formal offer to the Glazer family.
Ratcliffe is one of Britain’s richest people and is bidding to buy a majority share of the 20-time English league champions. His meetings come as the potential sale enters its next phase after bids were submitted via American merchant bank Raine last month.
Representatives of Sheikh Jassim bin Hamad Al Thani met with United executives on Thursday. The chairman of Qatar Islamic Bank is aiming to take 100 percent ownership of United and has plans to invest in the stadium and training ground.
Ratcliffe has said he would take a “fan-centered approach” to ownership and that he is “focusing on winning the Champions League.”
It is still not certain if the Glazers will cede total control of United as it considers “strategic alternatives.”
The American family, which also own the Tampa Bay Buccaneers, bought United in 2005 and has resisted repeated attempts from fans to drive them out.
Last year, Raine handled the sale of Chelsea to Todd Boehly and Clearlake Capital for about $3 billion.
