Unai Emery has completed his fifth summer signing since taking over at Arsenal with the Gunners having completed the signing of Matteo Guendouzi, the Mirror reports.

Despite the club not announcing the signing yet, leaked video footage has emerged of the French youngster signing his deal at the Emirates.

The footage shows the 19-year-old sat next to Arsenal’s head of recruitment Sven Mislintat and contract negotiator Huss Fahmy.

Guendouzi is believed to have put pen to paper on a five-year deal with the Gunners after being persuaded to leave Lorient in his homeland of France.

It is reported that it was Mislintat who identified Guendouzi as a potential summer target for the Gunners, but reports in France say that Emery was responsible for convincing the youngster to complete the move.

When announced, Guendouzi will be confirmed as the fifth arrival at the Emirates this summer.

Arsenal have already completed the signings of Stephan Lichsteiner, Bernd Leno and Sokratis Papastathopoulos and yesterday announced the signing of Uruguay international Lucas Torreira.
