It was believed Manchester United had made a loss of £15 million on Angel di Maria when they sold the Argentinian star to Paris Saint-Germain.
However, a report from corporate FX broker, Foenix Partners, claim the Red Devils actually made a quite significant loss of £22.5m on the former Real Madrid star.
The 27-year-old ended his short spell at Old Trafford in the summer, as he linked up with former Manchester United defender Laurent Blanc in Paris, and due to the low rate of the euro against sterling, the Red Devils took a significant hit.

As per the Independent, a statement from the broker read: "When Manchester United bought Argentinian winger Angel Di Maria from Real Madrid on the 26 August 2014 the cost was £59.7m at a rate of 1.2558.
"When the club sold the same player to Paris Saint-Germain for just £44.3m on 6 August not only did they lose £15m on the player, but they are also likely to have lost a further £7.5m (exact figure is £7,575,300) due to the exchange at the time."
However it was not all bad news for United fans as the weak rate of the euro led to the Red Devils cutting the cost of new arrivals Memphis Depay, Matteo Darmian, Bastian Schweinsteiger and Anthony Martial who all arrived from the continent.
The 20-time Premier League champions still spend close to £100m on new arrivals this summer and will be under pressure from their fans to improve on the fourth place finish last season.
It proved to be a weird final 48 hours of the transfer window as Javier Hernandez and Adnan Januzaj left the club and United, who are already short on attacking options, replaced the two departures with one addition, in the unproven Martial.
