Arsenal have confirmed the signing of Brazilian Under-19 captain Denilson from Sao Paulo, subject to international clearance.
Whilst most of the transfer deadline day focus on The Gunners revolved around the high-profile arrivals of Julio Baptista and William Gallas, Arsene Wenger also added the promising midfielder to his ranks for an initial £1.9 million.
The 18-year-old played just 12 times for his previous club and Sao Paulo say they expect Denilson to be loaned out to a European club in order to gain experience.
Arsenal could pay a further £1.1 million depending on Denilson's future performances, and the Brazilian side say they are happy with the deal.
"We have sold an 18-year-old for the same price as an experienced player," said Sao Paulo director of football Marco Aurelio Cunha told the club's official website.
"The deal is highly profitable for a player of his age.
"The deal is very satisfactory as we could receive profits in the future.
"There are some clauses which benefit Sao Paulo as we are the team where Denilson was born as a player."
Denilson will join compatriots Gilberto and Baptista at the brand new Emirates Stadium as he looks to impress in England.
In his short career to date the midfielder has skippered the five-time world champions at Under-17 and Under-19 level, and was recently called up to the Under-20 squad.
