That happens to a lot of young players. Similar thing has happened with Cleverley, who can have an average spell but he might do once pass which will be raved about, Carrick on the other hand did a great first time ball to Rooney yest but I've not seen much about that, if it had been Clev it'd be talked about as exactly what we're missing from the team etc.
Even when Jones was doing his bursting runs I said he lacked a purpose to them. I like him and think he'll be a top player, personally I think some of the roles asked of him this season he's either not been ready for or suited to and as a result he's taken some stick. Either way though going back to his earlier attacking play we haven't seen that in a while. He seems to stay behind the winger now rather then get beyond him, which means that it's valencia passing the ball for Jones to cross rather than the other way round, and his supply has been poor there for a while, and I think in a game when we needed goals, however low a chances of getting enough were, he was a poor choice to start there, and in general whilst he plays like this, we lose a lot of threat from that right hand side. It's not his fault cause until this season he's not really gonna have played there much, which is why I questioned the decision, in a similar way to why Park played behind Rooney against city.
