Rangers striker Daniel Cousin says it will all be about self-belief as they prepare to face Barcelona in this week's Champions League group tie.
"He was at Monaco in those days which was a bigger club than where I played at Martigues so obviously people were aware of his qualities.
"But it wasn't until he joined Arsenal that his ability shone.
"Henry has come a long way and he deserves the success he is enjoying.
"It's a thrill to play against the best players. We have home advantage so anything can happen.
"We must believe it can."
