So everybody seems to think. I on the other hand seem to be one of the few people who thinks that there's more to it than that.
There seems to be this idea that if we picked up Falcao we'd be deadly. I really can't see it.
Whilst Torres not being good enough to lead the line for Chelsea is pretty clear, I agree they are missing more than that. They need some higher quality personnel in central midfield, especially since Lamps has faded away. Been relying way too long on Ramires/Mikel and it's been a surprise it worked so well during the first part of the season. Mikel definitely stepped up his game but Chelsea would be looking for something more. Someone of Essien quality at his peak. Romeu has looked terrible when given the chance to play this season.
Central defence is another point of concern for sure. Terry is out, no one knows if he can come back at his best. Even then, he's not getting any younger. Luiz-Cahill is your best duo and it's looked shaky quite frequently.
Chelsea have been over reliant on their magical trio. It's felt like Hazard/Oscar/Mata, Cech and the fullbacks have been carrying the team for a while.
Moses and Marin could possibly offer more options to RDM, no idea why he doesn't play them much. Marin looked promising during pre season.
