ummm as a first choice CB, I would stick my neck out and say yes!
Real won the CL last year with Pepe, Ramos and Varane as their CB options. Till few weeks back, Chelsea were running away with the league with Terry and Cahill. City play Mangala there. Barca play the likes of Mascherano and Pique.
My point is, a lot more than individually world class players go into the making of a side that can compete for honours. This same Cahill Terry partnership looked so shit pre-Mourinho that people expected Terry to call it a day.
Under the right setup and more importantly continuity in partnership which is very very key in defence, the sum of parts in defence looks better than individuals.
I know Smalling divides opinions here but in him I see a player who has immense potential. What he needs is a stable partner to play with in the right setup and more importantly, luck with his injuries. If he gets these 2, he'l surprise a lot of people here. This is why I believe we only need 1 CB if the likes of Smalling and Jones can stay fit. I'd love Godin here, much rather have him than Hummels. Him and Smalling in a middle 2 would be very good.
