We're a preseason in with a manager known for developing talent. We haven't even seen all our signings actually play a full game yet. We haven't been able to play the formation we've played in preseason. Just give it a little...
Once the signings who are meant to be starters get in, then less pressure on some of the current guys and better suited on the bench as impact roles, then the system starts making sense. The hard work and repetitive positive motions become results, etc.
Would it have been great to have them do what Cesc and Costa did the first game they played? Sure. But - these are younger players, there has been more disruption, and they are getting there. We've looked better. That is a start.
