This should be for combined Rano-Juan thread, but as I said in December, Rano is still not a world class defender as much as some would like to think. Same goes for Juan. They are talents and quite exciting, but people need to tune down on talking about their current level because we've seen that they still have more bad games than you'd be able to allow. Some of their mistakes we choose to ignore, some are obviously undeniable.
And as I said many times with stats (seeing as Rano has the high rating on WhoScored), they are pointers, but you can get the real story only if you analyze him (and do so critically - rather than trying to prove that the stats/initial praise is right, you try to prove that the stats are wrong and after the observation, you determine where the truth is).
