Is a midfield trio of Thiago, Bruno and Pogba good enough defensively against the top teams? Probably not, but why is that an issue? Thiago as the deepest midfielder will definitely work in games where we dominate possession against deep blocks. Ole played Fred as the deepest midfielder in our last 2 games (one against a Sevilla side who are better than the majority of teams in the premier league) and the two goals we conceded in those two games both came from poor marking on behalf of our defenders as opposed to because we were cut open through the middle. Thiago is significantly better than Fred defensively and infintely better than him at almost everything else. Games at home against the weaker teams in the league we could definitely play Thiago/Pogba/Bruno and in the games where we can't or shouldn't then we have players like Matic and VDB to fill in. It's a 60 game season and injuries/fatigue are inevitable.
I'd understand the confusion and dismissal if we were talking about 99% of midfielders in Europe who don't play in the ilk of Matic as an anchor given we have just signed VDB but Thiago is probably in the top 3 best CMs in the world right now. I wouldn't like either sitting on the bench but the reality is he's better than Pogba and Bruno and is supremely gifted at almost everything you'd like a midfielder to do, a proper world class, rolls royce of a player who we all just watched stand out as the best player on the pitch in the Champions League final on a pitch with Neymar, Mbappe, Lewandowski, Muller etc. I don't think we'll get him but IF we have a chance we should be all over it. He's been very underrated on here.
Also reminder - the last time we won the league we played a midfield of Carrick, Cleverley and Rooney for the most part, are they legitimately better than a 3 of Thiago, Pogba and Bruno defensively?
