Arguably most of our squad need 'replaced with better' but under the right coaching set up, I see a hell of a lot more potential improvement in Anita than the likes of Williamson, Gouffran, Riviere etc
He is already an improvement on those three knackers you mentioned, he isn't as bad as them, just a nothing player, someone you forget is even playing.
So you forgot he was playing so much, that you exclusively complain about his non-existent performance. And can talk about everything you didn't see, nice one.
