The silky Real Madrid attacker has been on the verge of joining the French champions for the past few weeks, but his proposed move is understood to be stalling.
PSG are thought to be desperate to get money in before they commit to a deal worth around £60m, but this is leaving the player himself feeling frustrated.
Di Maria is keen to sort out his future, and United are ready to present him with a quick fix.
Louis van Gaal is said to be eager to bring the 26-year-old to Old Trafford, however a lack of Champions League football has been a major factor.
The deal on offer from the Red Devils would give di Maria a major pay hike, yet it’s unclear as to whether or not PSG are willing to hand him more cash.
The Parisians may raise funds by selling Ezequiel Lavezzi to Liverpool and offloading big name players such as Javier Pastore and Edinson Cavani.
