Manchester United have agreed a sensational deal to sign Colombia striker Radamel Falcao on a season-long loan from Monaco, according to widespread reports on transfer deadline day.

The prolific 28-year-old forward, who missed the World Cup with a serious knee injury, has also been linked with Real Madrid, Manchester City and Arsenal.

But several media outlets reported that United had secured his services, subject to a medical examination and Falcoa agreeing personal terms. 

It is believed that United have agreed to pay Monaco a fee of around £12 million (Dh72m) for the loan.

Falcao, who has scored 20 goals in 51 appearances for Colombia, is under contract at Monaco until 2018.

Since returning from injury at the start of the season, he has scored two goals in three matches, but he was left out of the squad for Monaco's 1-1 draw at home to Lille in Ligue 1 on Saturday.

If completed, the deal would leave United manager Louis van Gaal with a rich pool of striking talent at his disposal, as Falcao would join Robin van Persie and Wayne Rooney at Old Trafford.

Falcao joined Monaco from Atletico last year in a deal worth around 60 million euros (Dh290m), having scored 70 goals in 91 games during his time in Spain.

He scored nine goals in his first 17 league games with Monaco, but his debut season was curtailed in January when he sustained a knee ligament injury that forced him to miss the World Cup.
