The Brazilian defender is being linked with a move away from the Vicente Calderon.
The star central defender even confirmed he was interested in the move this summer, despite an excellent season with Los Colchoneros which saw him win the La Liga title ahead of Barcelona.
The deal however never came to fruition.
Miranda was pushing 30 so United were rightly unwilling to overspend on a player of that ilk, especially considering Atletico wanted them to meet his release clause - which stood at a whopping €30 million.
However reports last week began to claim that Atletico were now more open to the idea of selling the player.
The form of the 19-year-old Uruguayan Jose Maria Gimenez and his elder countryman Diego Godin has repoertedly convinced the hierarchy at the Vicente Calderon that Miranda is now surplus to requirements and if they receive a decent offer for his services, they will let him go.
Manchester United are now not believed to be the only team keen on his signature. Local rivals Manchester City are said to be gatecrashing the deal.
Today seemed to show the clearest indication yet that not all is well for Miranda at Atletico. In the 18 man team released for the fixture with Villarreal this weekend Miranda was not included.
His absence was construed by many to signify his imminent departure from the club.
However, that is simply not the case. while United and City fans would love it to be so Miranda has a slight groin strain so is unavailable for the fixture, rather than being cast asunder.
But that should not put off the Manchester clubs just yet. His future remains in doubt, so expect bids to come within the next month.
