Yeah, but surely real life comes into play when these prices are considered. Luiz is one of the top defenders in the league, of course he's going to be priced highly. Fellaini brought in bags of points last year, so he'll obviously be expensive as well regardless of how Martinez might use him. Toure is still one of the best midfielders in the PL, likewise with Aguero still being one of the best forwards in the PL. I don't think they're overpriced at all, they're all expensive and rightly so, because they're the best players in the league in real life.
