True, but it's an important aspect of our new manager's preferred game.
Anyway, Ronaldo and pressing: I mean, most people who watch him would presumably say that he doesn't consistently press and that his overall contribution to recovering the ball is very slender. And this is - absolutely and undeniably - supported by pure stats as well (he stands out negatively no matter how you look at it - a player who is famously called super lazy by United fans easily presses twice as much as Ronaldo in an average game).
This is by all means perfectly understandable - if Ronaldo had played like a pressing machine, he would've ran himself into the ground years ago. He plays conservatively in terms of defensive off-ball involvements and focuses on making dangerous offensive runs - again, this makes perfect sense for a player his age. But it's hardly a positive trait for an attacker if organized, non-stop pressing is your game (or an important part of that game).
In short, it's pretty obvious why people are questioning the idea of Ronaldo slotting easily into an ETH XI: everything points to him being a very, very poor presser who effectively has to be relieved of pressing duties to a great extent in order to play 90m week out, week in.
