Brazilian forward Wellington Silva says he expects to make an immediate impact when he links up with Arsenal in January.
Wellington is still just 17 but has agreed to join the Gunners once he turns 18 and is permitted to leave Fluminense for a foreign club.
The forward has represented Arsenal in reserve and friendly games and after spending a month training with the club is now heading back to his native Brazil.
Wellington feels he will require little time to acclimatise when completing his move to Emirates Stadium, where he will follow in the footsteps of Gilberto Silva and Denilson.
"The experience in London was perfect," Wellington said in The Mirror. "I can now dream of playing in the Premier League and I don't think it will be hard for me to adapt.
"Mr Wenger has spoken with me and has helped me with my work and training. I am really looking forward to this challenge. It's a great opportunity for me in my career."
