Poyet’s assistant, former Tottenham defender Mauricio Taricco, has also agreed a new five-year deal.

Chairman Tony Bloom told the club’s official website, www.seagulls.co.uk: “This is great news for the club.

“Gus and Tano are key to all of our immediate and long-term plans. When you consider the position the club was in when they arrived, what they have achieved here in less than two years is outstanding.”

Poyet added: “I am delighted to extend my stay here as the last two years have been absolutely fantastic.”
