Smalling is becoming world class if you can't see it than I am afraid you have no football knowledge, no disrepspect..
it's not that we sign player and he will become world class, center backs need time to develop, when you have Vidic and Ferdinand ahead of you in the pecking order you know you won't have many games, and when you're injured or played as RB that doesn't help you that much. Right now he's no1 CB, he's the best physically & athletically built center back in the league, he's gaining confidence finally getting games in a row and that helped him develop massively, I think he's actually a mix of Rio and Vida, great strong tackler and fantastic in the air like Vida but with little bit of elegance and athleticism like Rio who was also very fast in his prime. He doesn't need to posses any playmaking ability IMO, with the abilities he has he's all good, he's pretty good bringing the ball out of defense too, we need to pair him with other type of player who can add a little bit of technical ability IMO but I wouldn't be so rush going in the market, we already bought Rojo, who can develop and Jones albeit is quite stupid can still develop into great player, both Rojo and Jones are better than for example Koscielny in the beginning, they have potential to be better but they need to play and cut off the mistakes they do and that takes time.
And I very much doubt that you know all great center backs in Europe, it's very easy to see an odd game and judge players by that. On the other hand you have Smalling and co, you see them every week in underperforming team (3/4 of the season) and see every mistakes they make. Laporte, Hummels, Boateng and other players, they all make mistakes, I very much doubt you see all them play 30 games a season, unless you are scouting them for money..
So it's really easy to say Smalling and co are becoming top players for too long and so never will but they need time, and Smalling clearly starting to fullfill his potential at the age of 25 he can play till the age of 33 on top level with his stature.. He's also proven in the fecking premier league unlike some Spanish technical league.
Smalling + Rojo/Jones, McNair, Blackett. If Evans stays he will be a fourth choice and probably the best fourth choice in the league. He didn't say his last words, he can turn it around like Young, Fellaini, he once was the best center back in the league 3 years ago or so.. people forget good things about palyers and concentrate on negatives..
We're good with that set-up
