But soon, Mourinho's approach was punished.
Or rather, his control over his own team still needed to be strengthened, and his players' understanding of him was also insufficient.
Because of the dispute between Mourinho and Ronaldo, it even affected the on-field performance of their players.
As Deng Kai was preparing for the free kick, offensive and defensive players frequently clashed at the edge of Porto's penalty box, leading the main referee to blow his whistle multiple times to mediate.
This could cause the defensive players to lose focus, or to focus too much on certain players.
Bang!
Deng Kai took a tactical free kick, something the fired-up Porto hadn't anticipated.
By Deng Kai's side, Guardiola made a forty-five degree cross, sending the football into the penalty area.
Drogba, Ronaldo, and Kaka were tightly marked.
But Vidic, a tall focal point, was left unguarded.
Bang!
Vidic didn't even need to jump to head the ball.
