Manchester United are believed to be on red alert, following reports that Real Madrid are willing to let winger Angel di Maria leave for €60 million.
Having already brought in the likes of Toni Kroos and James Rodriguez from Bayern Munich and AS Monaco for a combined total of around €110 million, Madrid are now reportedly keen on landing Colombian striker Radamel Falcao.
And in order to raise additional funds for the transfer, Los Blancos are reportedly willing to sell di Maria for €60m, according to Goal.
Although the Argentine was brilliant for Madrid last season as the club triumphed in both the Champions League and Copa Del Rey, he has become surplus to requirements, following the arrivals of Kroos and Rodriguez.
And Madrid, who are in need of a new forward following the departure of Alvaro Morata to Juventus, are understood to be willing to cash in on the 26-year-old.
The recent development has reportedly attracted the attention of United and Paris Saint-Germain, who have both been chasing di Maria this summer.
However, United are in a better position to sign the winger as PSG are reportedly looking to secure the Argentine on a loan deal this summer, with an option to make it permanent next season.
The free-spending French giants are currently in trouble with UEFA over Financial Fair Play regulations, having already spent around £50 million on Chelsea's David Luiz.
When asked whether PSG would sign di Maria this summer, manager Laurent Blanc replied: "I will leave you to speculate. At the moment nothing is done. Are there negotiations? It's not for me to say but for the board of the club."
The Red Devils, on the other hand, have enough funds to negotiate a straight cash deal with Madrid.
van Gaal, who is currently analysing his squad's strengths and weaknesses, reportedly feels di Maria's addition will bring balance to the team.
It is also believed that the Dutch boss is not satisfied with the performances of United's current wingers Nani, Ashley Young and Antonio Valencia.
