Colombia striker Radamel Falcao has sealed a shock deadline day move to Manchester United.
The deal was only confirmed at 1.30am, after United applied for an extension from the Premier League in order to complete the paperwork.
Falcao signed on a year's long loan from Ligue 1 side AS Monaco, with an option to buy.
The 28-year-old described United as the 'biggest club in the world', upon signing, with his transfer confirmed by the club's official website.
New manager Louis van Gaal communicated his reaction to the deal, expressing his satisfaction.
"I am delighted Radamel has joined us on loan this season. He is one of the most prolific goalscorers in the game.
"His appearance-to-goal ratio speaks for itself and, when a player of this calibre becomes available, it is an opportunity not to be missed."
United moved Javier Hernandez on loan to Real Madrid, and sold Danny Welbeck to Arsenal, in light of the Colombian's switch.
