Watching: Cristiano Ronaldo scored the winning goal against Manchester United. The Real Madrid player spoke after the match that saw his return to Old Trafford: "I'm happy to win but also sad for Manchester United. I didn't celebrate the goal but I was happy inside. I have a lot of respect for the support that the fans gave me in my six years in Manchester. The most important thing was to win and we are very happy. I've done my job, which was to help Real Madrid win and go through to the quarters. I scored at the Bernabeu and I've done it again here".
