Jose Mourinho believes a refereeing blunder proved costly in Real Madrid's Champions League draw with Borussia Dortmund on Tuesday.

Jose Maria Callejon found the net early in the second half, but he was ruled to be offside, despite Mourinho protesting that it was a legitimate goal.
"I have to say I'm disappointed with this draw," he said. "Because we scored three good goals and only two were given.
"Jose was great and scored a legal goal. He was fresh and dynamic. The team did a great job, and the fans were behind them all the way. If I was one of them, I'd have loved to watch a game like tonight's."
Real remain one point behind Group D leaders Dortmund, but Mourinho denies finishing second will hamper his side's chance of becoming European champion.
"I have won the Champions League before when my teams have come second. It's not a problem," he said.
Real defender Pepe cancelled out Marco Reus' opener for Dortmund and he was forward in praising the Germans as a force in Europe.
"They are an excellent team," Pepe said. "They like to play football, so it's been a very hard match for us.
"The second half we dominated, but they are a very difficult group, we just kept on working. We still have Manchester City to play, so we have to believe in ourselves to win the group."
