I think the score was not really indicative of the performance. We played excellent the first 15 minutes, but after that it was moments of individual brilliance, rather than intricate play, that allowed us to score.
For whatever reason, after we score we seem to struggle to play fluidly. We slow the game down more than we should and get sloppy in the final third. The "killer instinct" that some people mentioned is playing the same as we did in the first 15 minutes of this match throughout at least 75% of the match, regardless of what the score is. I'm pretty sure that's what Ange wants too, but we're not there yet.
