Arsenal manager Arsene Wenger says he is "certain" former Gunners captain Thierry Henry will return on a two-month loan deal, if details can be finalised with Henry's current club New York Red Bulls.

Wenger says Henry would offer back-up to captain Robin van Persie, with strikers Gervinho and Marouane Chamakh set to depart for the Africa Cup of Nations in January.

The 34-year-old Frenchman is Arsenal's all-time leading goalscorer, with 226 goals in 370 appearances for the club before switching to Barcelona in June 2007 and moving to Major League Soccer in 2010.
