Henry has signed a short-term loan deal from the Major League Soccer’s New York Red Bulls.
The move to bring back the 34-year-old former France international, who left the Gunners for Barcelona in 2007, had long been expected and he will now be for the FA Cup game on Monday.
Manager Arsene Wenger told www.arsenal.com: “I am very happy. It was my desire and Thierry’s desire. We will have Thierry for January and in February. Then he will go back to the United States.”
