K.Toure, Lescott, Nastastic, Mangala, Demichelis...
Seems to be a pattern emerging on that left hand side. I think Vinnie should count himself lucky that he has Zabaleta on his side. Kolarov/Clichy are a problem... and left back has been a major one that has been ignored since the Hughes era. Neither were any good defensively. Barry's role was critical and often went unnoticed.
There was always questions raised over how he got in our starting 11 so often. Mancini knew fully well that defensively on that left hand side, it was vulnerable. Barrys role was simple, just sit. Garcia was then brought into the fold in hope he could replicate what Barry did but just offer that bit more, instead, he was worse. Then Fernandinho came in, a great player no doubt as proved in some elements last season, but not the same holding midfielder that Barry was and what he offered was good but not what we were after. We had turned into a side where we went out to severely outscore the opposition. We can't do that now. What Barry did looks more obvious now than it did when he was here.
It was the right time to go for him, he was starting to age and errors were creeping in, especially in the CL which was where we desire to succeed. But he was never replaced. We were fortunate Negredo and Aguero were firing on all cylinders last season, because defensively we haven't been up for it in some time. Just like dominos, when one goes, the rest also fall. And the centre half on that left hand side has been carrying the left back ever since Barry left the club.
