Arsenal boss Arsene Wenger says his players will benefit from training with New York Red Bulls striker Thierry Henry.
Henry has returned to the Gunners to keep fit during the MLS offseason.
"Thierry loves football, and he loves Arsenal," Wenger said.
"To practice with us for him is a pleasure - for him and for us.
"I think it is an honour and a pleasure. An honour because he is a legend at the club and he is coming back, a pleasure because when he is on the football pitch, he is still a great player."
