Where the Champions League final will be won and lost It' ll be Real Madrid joining Juventus in Cardiff on June 3 for the Champions League final The time winners and current holders will be looking to break a year. The usual suspects, like Barcelona, Real Madrid and Bayern Munich will always be favourites to win the Champions League. After all, they have the best players. I suspect this may finally be the year a team successfully defend the Champions League. Real Madrid are a hard-nosed, winning juggernaut.
