2011-2012 Ronaldo scared the living shit out of me, Ronaldo post 2013, not so much. If he's having success an scoring against us it probably means we're playing very poorly defensively and in the middle of the park allowing for his teammates to find him with space. These days if you block off the passing routes to Ronaldo in the box you effectively silence him.
Ronaldo exposes any slight bit of poor defending even from the best sides in world at it.
Is best I have ever seen for movement off the ball and he is doing it regularly to the best teams not just Barca.
It is virtually impossible to stop the supply to him as if push high he gets in behind you and if sit deep he will most often exploit that one or two moments teams defend even slightly badly.
Not that you are saying it but this idea he is a tap in merchant is clueless and if it was that easy there would be plenty of players doing it.
