Gets roasted multiple times in this vid. The one where saka just ghosts past him at 1:50... Ouch
Just to add something balanced (I hope) that I mentioned in another thread.
Rodri does all the things that Pep would have asked Busquets to do in his prime, but back then, heavy pressing football wasn't as prevalent as it is now, and speed is more important now than it ever was.
Rodri makes use of his frame in many ways though. Aerially he is quite good, he is good at intercepting due to his long legs, and his passing short and long are very good. He is also good at keeping the ball under pressure and using his body to stop getting dispossessed, and can play out from the back the way Pep wants.
That's alot of praise for Rodri right there. But...
He has to work more on the defensive side where his speed is a weakness. I don't think its insurmountable, yes he won't get faster, but he can position himself better as he gets older and smarter.
From my watch of the game after the fact, him getting roasted over and over again by Saka was the biggest negative I noted from City in the first half (only watched first half). He also let a ball slide through and Saka got a good chance on target where Rodri instead put his hands up.
In that clip above for example, you can see that even though Saka is a quality player who uses his speed well, if Rodri literally positioned himself a little better, then Saka doesn't get by him and Rodri doesn't have to foul so constantly.
That's my 2 cents on it, don't want to pile up on him, and I did praise alot of his good qualities.
If that defensive side improves, basically through awareness and position as speed wont get better, he basically becomes the worlds best DM because the rest of his game is so strong.
