Former Colombia striker Faustino Asprilla believes Falcao was just what Manchester United needed to achieve their objectives.
The 28-year-old joined from Monaco during the summer transfer window and is expected to be on the bench when the Red Devils host Queens Park Rangers this week.
"I think it's fair to say Falcao's move to Manchester United took everybody by surprise," Asprilla told Sky Sports.
"I'm sure they have selected the right man to help the team.
"He's a great goalscorer, a natural finisher and he is among the best in the world in that position."
Concerns were raised about the fitness level of the striker but Asprilla believes he fully recovered from the knee injury that kept him out of the World Cup squad.
"He will be fine [physically]," added Asprilla.
"He has had ample time to recover and his therapy has been great so he should be 100 per cent.
"I'm sure he will do very well for Manchester United."
