They are basically a very average team now. They're football has been very surprising. In games against Arsenal and Bayern, they played a more counter attacking style which is opposite to what Enrique likes.
His teams are normally possession based but this is what happens when you dominate the ball in your league and come up against better opposition in the CL.
I think you should think of them more like United now, in that they had a period of signing massive names/paying silly wages and it's really only been a season and a few months since the change in policy. Their recruitment, outside of attackers, in my mind has been really good and I can't think of a squad of 18-23 year olds in world football which is better? Zaire-Emery, Beraldo, Barcola, Neves, Doue, Mendes, Pacho etc. It was only a year and a bit ago they had Messi, Paredes, Wijnaldum, Neymar, Veratti, Icardi, Sergio Ramos all leave together.
As someone pointed out though, their forwards I see as distinctly average - Ramos and Muani combined cost like £130m, they are quite young but I feel that is where they let themselves down big time (and if you look at a lot of their games, they really struggle to convert chances just like United). I'd also mention their easiest games are to come, they lost away to Arsenal and Bayern (probably better teams in general than them now), they drew with PSV (their main bad result) and lost to Atleti though it was about as one sided a game as you'll see. They should still go through but they will go out once they meet one of the better teams most likely as they struggle to score.
