Radamel Falcao is set to join Manchester United on loan after the Premier League club agreed to a loan deal with Monaco, a person with knowledge of the deal said Monday.

The Colombia striker's season-long loan deal will cost United about $9 million and is subject to a medical examination and personal terms being agreed to, the person told The Associated Press. The person spoke on condition of anonymity because the deal has not yet been completed.

Premier League clubs have until 2200 GMT Monday to sign players before the transfer window closes.

United's need for reinforcements has been highlighted by the failure to win any of its opening four matches under manager Louis van Gaal, who had been hired to halt the decline under David Moyes last season. United's latest setback was a 0-0 draw at Burnley on Saturday, following a humiliating League Cup loss to third-tier club MK Dons.

Falcao, who signed with Monaco a year ago, would be joining a United side out of the Champions League after last season's seventh-place finish.
