I fell a bit in love with Celtic, because the atmosphere was amazing and the crowd was magnificent, the way they behaved with the Porto fans.

He's a specialist in failure.

The team is completely close. Anything you say outside, there is no chance it will go inside. So the team is really strong and compact. We know what we want and how to achieve it on the pitch.

As we say in Portugal, they brought the bus and they left the bus in front of the goal.

If you want me to rule out ever being Manchester United manager, I can't. Special clubs need special managers, so in theory it could work.

I hate to speak about individuals. Players don't win you trophies, teams win trophies, squads win trophies.

In my teams, when we win, we all win, and when we lose, I lose.
