Radamel Garcia claims his son chose Manchester United ahead of a clutch of other clubs as interest in Falcao peaked on deadline day. Juventus, Manchester City, Arsenal and Liverpool were all keen on the forward in the dying hours of the window.
But Falcao decided to join Louis Van Gaal's side, something his father claims was a relatively easy decision.
"Thank God, everything happened with Manchester United," Radamel Garcia said as reported by the Daily Star.
"Radamel is a person who has done many things in Europe and has always deserved the best for all his efforts and sacrifice in his career.
"Manchester United is the most important team in England and one of the most powerful financially. Now he must perform at his best to continue winning.
"Fortunately he has adapted to European football and in the teams where he has been in Argentina it was easily done too. Juventus, Manchester City, Liverpool also approached him and Arsenal at the last minute.
"Fortunately he ended up at Manchester United, a great team that he has to lead forward."
Falcao player profile
Falcao in, Hernandez out
On a frantic last 24 hours of transfer activity, United officials sealed a dramatic loan swoop for the Colombian international with Javier Hernandez heading to Real Madrid to open up space in the squad.
The Spanish giants had been contenders for Falcao's signature, but in the end went for the cheaper option after spending big on his former-Monaco teammate James Rodriguez.
Reports have suggested that the total cost of the deal, including wages and the loan fee, will see United spend in excess of £24m for the player's services for a single season.
It's an expensive gamble considering the 28-year-old is coming off knee surgery, but United need something to spark their season into life after a sluggish start. A top four finish and a return to the Champions League is a priority for Van Gaal.
