The former Reading assistant 'raided' his old club this morning to re-unite him with the player who it has been speculated that he has been long chasing.
Bees fans see Brooker as an essential piece in the first team jigsaw and as a good replacement for John Salako who was released at the beginning of June.
The player made twenty-four appearances for the Royals last season and Allen believes that his creativity will aid Brentford to solve their goalscoring problem which halted their playoff progress last season.
Speaking at the unvailing of his new signing Allen said,
"I believe that Paul can add the required more creative feel we need this year, he can play on either wing and is two footed which is a great bonus"
"We've been looking at bringing him in for a while but many other clubs have been intrested him, but i'm very pleased and relieved he chose Brentford" said the boss."
The twenty-eight year old has signed a three year deal at Griffin Park and will join up with his team mates for pre-season training next week.
Allen finished by saying,
"He has good quality in the final third and he will definetely be an asset to the club, with the right support I believe that he will become a vital player for us."
