As they cast around for last-minute additions - with the summer's transfer work only yielding Lee Grant, Fred and Diego Dalot so far - United have made a late move for Godin, according to Sky Sports News.
On Thursday morning, several reports claimed that United had contacted Atletico in the hopes of adding Godin to their squad before the 5pm deadline.

However, within hours, Godin had signed a new contract on improved terms at Atletico Madrid earning him £6.75m (€7.5m) net a year - something Atletico are yet to formally announce.
But Mourinho told reporters at the beginning of deadline day that he didn't anticipate any new arrivals at Old Trafford.
Godin has spent the majority of his career in Spain, joining Villarreal in 2007 before moving to Atletico Madrid three years later and becoming an integral player, winning six trophies including the La Liga title in 2015 and two Europa Leagues.
