Saïd, as he is generally known, completed a medical earlier this week and finalised his move to England this afternoon, subject to international clearance. He has signed a four-year contract, keeping him with the Bees until the summer of 2022, and there is a Club option for an extra year.

Saïd, who will be 23 next month, was born in Algeria but has played his entire career so far in France. He joined Nice as a teenager after playing his first football in the youth ranks at NRB Bethioua. He made his debut for Nice just past his 18th birthday, in October 2013, and scored his first goal the following season, while still 19.

Saïd, who has a French passport, played for Nice in the French top flight and has also had three loan spells. He spent part of the 2015/16 season on loan at Angers Sporting Club de l'Ouest in Ligue 1 and then the second half of the 2016/17 campaign at second tier Gazélec Football Club Ajaccio. Saïd was at La Berrichonne de Châteauroux last term and scored ten goals in 33 games in all competitions.

The 22-year-old can play across the front line but has spent much of his career to date playing on the right wing. He has earned one Algerian cap, in 2015, and leaves Nice having scored three goals in 18 games in all competitions. He played 17 of those games in the top flight.

Rasmus Ankersen, Brentford FC Co-Director of Football, said: “Saïd is a player with lots of potential. He has the pace and technical skills to cause many Championship defenders problems, and we are pleased that it was possible to sign him early in the window so he can now go with the rest of the team to the pre-season camp."
