I really think Madrid is the best matchup for juventus out of the three, bayern and barca like to play from the wings, also have flexible players in the likes of neymar, messi, robben, thiago etc... Madrid actually plays more a physical football with many long balls, set pieces which suits juventus more in my opinion. This will be closer than many people think, it will be no easy run for madrid. Juventus can hurt Madrid, stay compact with a good defence and try to hit them fast when you have the ball, the switch from defence to offence will make the difference, and this battle will be decided in the midfield, the likes of vidal and marchiso must win the battle there against kroos and isco, and deliver to tevez and morata. Madrids defence is just good when you give them the time to settle, which our mistake was last year, playing the ball back and sidewars was wrong, you must win the ball and then surprise them, no fear of going forward, attack after winning the ball, and I believe tevez or morata can surprise them by playing fast and direct... its important to attack them, if juventus decide to hide deep and just defend without fast approach they will get knocked out just like atletico. They are vulnerable at the back, fucking Schalke put 4 against them in MADRID, dont forget that!!!
