Francis Coquelin says Thierry Henry has already had a positive effect at Arsenal.
Henry will complete his loan deal from New York Red Bulls once a delay in paperwork is resolved.
And French midfielder Coquelin, 20, said: "The first time I saw Henry, he really impressed me - his arrival will be a bonus for the whole team.
"You can tell he's up for it and he's lost none of his quality. It's already a real plus point for us in the changing room."
