Still a way to go, they should really have sorted it out. James Rodriguez or Falcao I'd say would be the best options for them. Hell I'm sure they could always bring Jo back....
He was massively over-rated and has played a very small part in their success over the last few years compared to Aguero, Tevez, Dzeko, etc. Also this is a ridiculous topic to be on our board so I'm moving it.
