It is a timely reminder of the former Atletico Madrid star's goalscoring skills, and comes after a particularly difficult period at Old Trafford.
The 29-year-old hasn't scored for his loan club since a win over bottom club Leicester City in January, and has even turned out for the reserves in an effort to return to some match sharpness.
He has just 4 goals all season, so will have surely welcomed being the main man for the World Cup quarter-finalists this international break.
Against minnows Bahrain, Colombia, led by Falcao, were able to demonstrate their goalscoring skills, and their captain helped himself to a brace in the 6-0 win.
Falcao's first strike was an expertly taken left-footed volley after being played through on goal, finding the far corner with ease.
He netted his second just a few minutes later, again breaking the Bahrain back line before his shot deflected off a defender and over goalkeeper Sayed Jaffer.
Earlier on in the game, rumoured Arsenal and Spurs target Carlos Bacca opened the scoring with his 7th international goal, which you can see below. The Sevilla striker has 19 goals in 40 games this season, and has been able to carry that form onto the international stage.
