Most games is exaggerated, if we look at PL's Top 10 teams right now...I didn't want to be the one to say it. But Kyle is a specialist player to me. Not an every game player.
I think we are a better team in most games with Rico over Kyle. And Kyle in special games against certain Superstar players like:
Mbappe, Leao, Vinicius etc.
But against bottom 10 teams it's possible to rest Kyle and play Rico...
People can't see that defensively Rico is still liability. Can't count number of times he lost simple balls during build up or even look at North Macedonia goal against England, stupid mistake in a very simple situation, but what can you do, size does it all.
Pep is correct, he is more of a midfielder than a defender and I can easily see him progress as a box-to-box, rather than fullback.
