You can really see his confidence building, even with little things like the give-and-go with Negredo followed by the cross on the byline or that effort he had from distance against West Ham. Not saying that these things make him The Answer or a better player, just that he seems a bit more comfortable in himself and is playing in a more proactive manner, which can only be a good thing.
He did his job very capably today, making some good tackles and interceptions, and took a bit more responsibility in possession than he has in the past. A good performance, all in all.
