Ribas returns to coach Penarol again
Ribas was sacked as national team coach of Oman after only three competitive matches last year and replaces Mario Saralegui, who quit in the dressing-room after losing to arch-rivals Nacional in a friendly on Saturday.
"This is a big responsibility and an opportunity for glory," Ribas told a news conference as he was officially presented. "I've always dreamed about this project and will defend it with my soul."
The volatile coach, who describes his players as gladiators and spends most of the game ranting at them on the touchline, was previously in charge from 1999-2001.
During that period he led the side to one Uruguayan title, but made more headlines when he was jailed for eight days for his part in an on-pitch brawl at the end of a derby against Nacional.
Nine players (three from Nacional and six from Penarol) were also held in custody and later ordered to do community service.
