The Real Madrid manager celebrated Cristiano Ronaldo's game-winning goal by taking a jubilant knee slide on the grass field while wearing an expensive Adolfo Dominguez suit.
Ronaldo's goal capped a 3-2 comeback victory over Manchester City in the UEFA Champions League.
All five goals were scored in the thrilling second half of the contest. Despite controlling most of the game, Real Madrid was twice forced to come from behind before Ronaldo's goal. Soccer fans around the world were bubbling with enthusiasm by the time Ronaldo scored the winner, and Mourinho's slide ended the affair with an exclamation point.
Real Madrid is off to a poor start in La Liga, winning just one of its first four games. Sunday's 1-0 loss to Sevilla FC left Real Madrid eight points behind FC Barcelona in the standings, and some say the title race is already over (with 34 games remaining).
Mourinho criticized his players commitment on Sunday, even going so far as to say "I have no team." The press conference led to rumors about a divided dressing room and Mourinho's intention to walk away from the job in the near future.
But Tuesday's win — and Mourinho's slide — suggest Real Madrid and its manager are ready to fight to retain their status as one of the world's best soccer teams.
