How? The guy just scored the winner in the last minute of a CL final, especially in his case after years of frustration, I thought it was a natural reaction, genuine and passionate. It's the biggest moment of his career and it was an amazing story to see him, after everything that happened in the last 3 years scoring that goal, it was like a perfect script.
As for Jose, they're on good terms, that's what Robben said about him last year:
Mourinho has helped turn me into a much better player. He contributed to my mental toughness and professional attitude. The player I am today is thanks to Mourinho. Robben admits that he was thrilled when Mourinho went up to him after the semi-final in the Bernabeu. He added: I can’t say anything negative about him now. I worked with Mourinho for three years and it was a great time. We also shared many great moments. And let’s face it, he is a fantastic manager. I can only compliment him for what he has achieved again at Real Madrid.
