Yeah I'm also of the opinion we can't really compare Bartra and Varane. Varane has established himself as a WC centre back that everyone is talking about, nobody considers Bartra a threat, yet.
Let's hope this season the tide changes and Bartra rises to the fore! But I have never rated Bartra THAT highly, I think he was our best CB last season, but in absolute terms, I think that says diddly squat, cause we probably had one of the worst defence out there.
People tend to throw the we conceded so little argument around, but that's being a little silly if you ask me. We are a far superior team than 90% of the teams in La Liga, and we dominate possession, and generally outclass teams (who aren't RM, Atletico, etc.)
leaving them with barely a few attempts on goal. However, on those few attempts we always looked vulnerable, everybody knew how shit we were at set pieces, and almost every counter attack against us looked like a goal because of Pique and a lot of times Masch.
Coming back to the point - Hope Bartra gets the time he deserves after being the best CB last season, but will he come anywhere close to being a top class defender that top teams would be wary of/want in their XI? In my head, I don't see that happening, but
hope I am proven wrong!
