Paulo Fonseca has been appointed the new coach of Porto on a two-year contract.
The Portuguese champions have acted quickly in naming Vitor Pereira's successor following the 43-year-old's decision to move to Saudi club Al-Ahli on Sunday.
Fonseca took control of Pacos Ferreira last summer and steered the club to the 2013-14 Champions League play-offs courtesy of a third-placed finish in his first season as a top-flight trainer.
"It is an honour to represent the champions. I couldn't be happier and it was an easy decision to make," he is quoted as saying by Uefa's official website.
"I have ambition. I usually like to play with balance and keep possession – that is the hallmark of my teams. I want my team to dominate at a high tempo, and for that we need solidarity."
Porto recently lifted the Primeira Liga for a third consecutive term, losing no games en route to their crown.
