Manchester United have agreed to sign Colombian striker Radamel Falcao in a $12 million season-long loan deal from Monaco, with an option to also buy the player.
Falcao has scored 11 goals in 20 league appearances for Monaco, and the 28-year-old has two in three games this season.
After their record signing of midfielder Angel di Maria, many United fans are wondering why manager Louis Van Gaal hasn't found much-needed defensive reinforcements.
Stalwarts Nemanja Vidic and Rio Ferdinand have left Old Trafford along with long-serving left back Patrice Evra.
Although Marcos Rojo and Luke Shaw have been signed along with versatile Dutchman Daley Blind, Van Gaal's defensive resources look thin.
Phil Jones, Chris Smalling and Jonny Evans have struggled to adapt to Van Gaal's preferred 5-3-2 formation and Van Gaal has been forced by injuries to play 20-year-old Tyler Blackett.
Meanwhile Mexican Javier Hernandez has been loaned to Real Madrid and Falcao's arrival has also allowed Van Gaal to offload England's Danny Welbeck to Arsenal.
The Colombian, who is joining United initially on a season-long loan, is a proven marksman.
He netted 41 times in 51 games for Porto, scored 52 goals in 68 matches for Atletico Madrid and 11 in 20 appearances for Monaco before a knee injury ended his season early and ruled him out of this year's World Cup.
United manager van Gaal spent more than $NZ 300 million in the transfer window including signing versatile Ajax midfielder Daley Blind for $NZ 28 million.
