Mandzukic goals won't happen if Madrid has a taller top GK.
DDG, Oblak, Cortois will save that. The ball was not heading to the corner of the net. And Navas only few inches misses the save.
No matter how good Navas is, no matter how flexible he is, the height factor for the GK is an advantage.
Wait for second half, Juve will play aerial football more. And note it, Mandzukic is higher than Ramos.
Oblak is actually only 1cm taller than Navas. I agree though. There's a limit to making up the height disadvantage. Yann Sommer is another good example for a good goalie who also suffers from being relatively short.
