Wales Under-21 midfielder Ramsey, 17, could have opted for Old Trafford instead of Arsenal, but the lure of working with Wenger, who has nurtured so many talents, proved decisive.
"I just had a gut instinct that the right move for me would be joining Arsenal. It was my decision.
"I thought about where the best place would be for me to develop as a player, and that was Arsenal.
"Arsene is a great manager and Cesc can make something happen out of nothing on the pitch."
