Poyet has been assistant manager at Tottenham, Swindon and Leeds
Former Tottenham assistant boss Gus Poyet has been confirmed as the new manager of Brighton and Hove Albion.
Poyet, who turns 42 on Sunday, accepted the job on Tuesday and has agreed a contract until the end of next season.
He told BBC Sussex: "This is another challenge for me to take the club where everybody in Brighton wants to be and that's in the Championship.
"Being realistic I think 18 months is possible. If that is the goal of the club it's no problem."
Speaking at his unveiling as Russell Slade's successor at a news conference Poyet added: "I'm not worried at all. Everything I've done in my career has been about winning football games and being successful."
Albion chairman Tony Bloom said: "When Russell parted company with the football club just over a week ago we had a lot of applicants, a lot of very good ones, and I had a lot of work to do to make sure this football club found the right manager.
"As soon as Gus Poyet was interested, I became very interested and everyone I spoke to [agreed] his reputation as being a top quality coach shone through, as well as being a top man."
The former Uruguay international midfielder started his playing career in his homeland with spells at Grenoble and River Plate Montevideo before spending seven years in Spain with Real Zaragoza.
He joined Chelsea on a free transfer in 1997, making 145 appearances for the club before transferring to Tottenham, where he spent three years before retiring.
