Nobody has shown me any stats.
Rodwell, Garcia and Fernando were bought in to allow others to rest, yet we've gone backwards over the last 3 years.
Garcia was a terrible choice to replace NDJ so wasn't going to rest anyone. It was clear from his youtube clips that he couldn't tackle and was terribly slow. Whoever scouted him and signed him should be ashamed. A well schooled defender could have done a better job in midfield, e.g. Boyata for all the abuse he got had better attributes than Garcia.
Fernando's footage and reputation looked a bit better but again it was clear that he was an obvious mistake after a few games. Again someone did a poor job in choosing him.
Rodwell I think was meant to be a squad player, unlike the other 2. Injuries screwed that up so I don't think anyone should shoulder blame.
I agree that we need first 11 capable players. IMO Delph is potentially that but whether he is just as bad a choice as the previous 2 can't be known till we see him play for us.
Ps I wouldn't blame the players for not being good enough. Same with Sagna and Kolorov. They should be treated respectfully but they should be replaced with better quality.
