As I've said before, Rodri looks like he fits the bill when we're flat track bullying dross, but there are still glimpses of some major weaknesses to his game even then.
We had 80% possession against a garbage 10 man Arsenal on the weekend, and the consensus seems to be that he played really well.
Despite that overwhelming dominance we had against Arsenal, Rodri still got turned about 3 or 4 times leaving us exposed at the back. Perfect example of that here, 15 seconds in:
This happens every single week with Rodri, and it's genuinely alarming. In the tightly contested fixtures against the better sides this gets punished, and we've seen it before time and time again. You get tested more out of possession and those flaws will be exposed.
It's a big weakness for us as far as I'm concerned, especially with Fernandinho's age. This position is a worry, and I fail to see how anyone else can honestly say otherwise.
There is no player on the pitch that you wouldn't be able to highlight an error for in a game or several games. Anyone with a fair lens would be able to find far more displays of outstanding quality, however. The stats tell us that Rodri is one of the very best midfielders in the league. Naturally, therefore, I disagree with you. As for Fern's replacement, hopefully, Lavia will fit that bill. Eventually, I hope that Rodri will be able to convince the small number of posters that remain scornful of his quality.
