The Leicester City defender has been the subject of a host of transfer rumours since his performance at the World Cup, and was previously as short as 1/2 (1.50) with William Hill to join the Red Devils.
However, interest from United appeared to have waned as they were reportedly put off by the transfer fee and just one week ago, the 20-time league champions were out at 4/1 (5.0) to sign Maguire.
United and Leicester face off in the opening match of the Premier League season on Friday night, providing an even more intriguing part of the saga.
William Hill also offer 8/11 (1.73) that Maguire stays at the King Power Stadium, and is certainly a possibility considering the Foxes have rejected big offers for Riyad Mahrez and Jamie Vardy in recent years.
It is no secret that United have been after a centre-back all summer and they also have interest in Toby Alderweireld and Yerry Mina, with a deal allegedly in place for the former.
|Club after Summer Transfer Window (1st Sept 18)||Price|
|To stay at Leicester||8/11 (1.73)|
|Manchester United||evens (2.0)|
|Manchester City||25/1 (26.0)|
As such, it is little surprise that the Belgium defender is just 4/9 (1.44) to sign for the Red Devils, although it is worth noting that the report also states Tottenham will not sell him until they have a replacement.
