The report says:
Despite speculation in recent months linking him with Chelsea and even with Real Madrid, the fact is that the Old Trafford club is the best placed to sign the Colombian forward.
Sources close to both parties suggest that a down payment may have already been made as a guarantee for a future transfer.
Marca go on to reveal that United's purchase of David de Gea was constructed in a similar fashion—a down payment was made on the player and Atletico Madrid had already collected the lion's share of the fee months before the player even arrived in England.
So what does this mean for Manchester United, and in particular for the Red Devils' striking corps?
Sir Alex Ferguson has essentially won the title this year after simply outscoring every opponent in his path. He made some tactical evolutions, and on occasion game-planned specifically for certain players, but it was largely free-flowing, 4-4-2, attack.
With four established strikers currently on the books, this transfer—should it happen—will send shivers down their spines.
Falcao has been hailed as one of Europe's premier strikers for just under two seasons, and his goalscoring record is scarily consistent.
In terms of goals yielded and reliability in the box, he's up there with the best. Few forwards have bested his efforts over the past few seasons, and those that do are the likes of Lionel Messi and Cristiano Ronaldo.
So after two years at the Vicente Calderon, Falcao could be bringing his poaching talents to Old Trafford. What does that mean for the current incumbents?
Robin van Persie is safe; He's the reason United have won the title this season and is just one year into his deal. Danny Welbeck, a product of the United academy and darling of the coaching staff, has a lot of improving to do next season but the Red Devils won't cut their losses with him.
But Javier Hernandez and Wayne Rooney are a different story.
The Mexican has found playing time hard to come by and was linked with a move away from the club in January, while Rooney is constantly dogged by drama.
Rumours of a possible United-Rooney divorce have circled for years, and the club never sell a star without replacing him properly (see David Beckham to Cristiano Ronaldo).
Falcao is one of the only men in world football that could replace Rooney at United, and you just start to wonder if this has more legs than at first thought.
Can you imagine RvP playing just off Falcao in Manchester red?
