Well no, I said he did well when he played in Iniesta's role, as well as in the more offensive way he started being used later on. I would definitely make a distinct difference between attacker and midfielder in this context, especially when you talked about the latter being similar to how he played for Spain, which was as a false nine. It's not that Fabregas didn't play well in midfield in general, it was that he didn't play well in the midfield role that he was expected to fill, which was Xavi's.
tl;dr he played as the passer, the creator and the forward in a 4-3-3. He did well in the latter 2, the first of which is still definitely a midfield role.
