Arsenal have completed a deal to sign Yacine Adli from Paris Saint-Germain, according to reports in France.
The 17-year-old midfielder is widely regarded as one of the brightest prospects in European football. Adli reportedly rejected the offer of a professional contract from PSG, which means he would be able to officially sign a deal with Arsenal when he turns 18 in July.
Arsenal will pay a €255,000 (£223,000) compensation fee to PSG in order to sign Adli.
According to RMC Sport, the midfielder has committed to a three-year contract with Arsenal, which also has the option for a further two seasons.
The youngster is the second signing for Unai Emery after defender Stephan Lichsteiner signed on a free deal.
