Real Madrid president Ramon Calderon is convinced their form this season is rattling their rivals across Europe.

Despite defeat at Sevilla and a stalemate at Olympiacos, Calderon was adamant: "I think European teams see us as a threat, it means that we are frightening them, we are making them afraid.

"I think the team is playing very well, it will be difficult to reach the final in Moscow, because there is a lot of competition, teams are very good , we will not find any easy rival to reach the final.

"But we have an obligation to try, and that we are."
