Maguire continued to forge a reputation as one of the best centre-backs in the Premier League last season and he carried that form in to the World Cup as he was one of England's star performers en route to their semi-final appearance in Russian Federation.
Mourinho is said to have doubts about both Chris Smalling and Victor Lindelof and also feels that the signing of Diego Dalot from Porto has relieved fullback issues sufficiently to allow the pursuit of a central defender.
"Maguire is still 8/11 to remain with the Foxes as Claude Puel plots improving on his side's ninth place finish last season, while a move to Tottenham looks unlikely with Spurs out to 13/2 having been the 2/1 favourites to sign him".
