Leyton Orient defender Romain Vincelot is confident new Sunderland boss Gus Poyet will be a success at the Stadium of Light.
Poyet signed a two-year contract earlier this week with the Black Cats after the club decided to sack Paolo di Canio after just six months in the job.
Vincelot, who played under Poyet at Brighton, believes his old manager has all the attributes to make a positive impact at Sunderland.
"He's in the kind of situation he was in when he arrived at Brighton, so I think he has the ability to do it," Vincelot said.
"Then it is the Premier League, so it is a big challenge for him, but I think he has everything to do it properly.
"He's a really good manager and a good tactician, really unbelievable. He gave me good advice and lots of good habits on the pitch."
