Meanwhile, young Costa Rican striker Joel Campbell has revealed his joy at sealing a move to the Emirates.
"Greetings to the Arsenal fans. It is a dream come true to play for such a big club in England and I want to do well for myself and Costa Rica. I am ready, I am very happy to be here and I want to focus on doing well for Arsenal,'' he said.
"Arsenal is a very well-known club in Costa Rica. I am making history because no other Costa Rican player has ever played in a team with the quality of Arsenal. Only one player has been in the Premier League before but not like the one I am at now.
"Arsene Wenger is a manager of immense quality. He knows how to use youngsters' ability. I have been watching Arsenal play since I was a kid and I took this decision because I know I have a possibility to become a better player here.''
