Henderson is the reason we've been playing a high-line the last few weeks.
The backline have been looking significantly more confident about pushing up, and that in turn helps the midfield and attack.
The way the team is building from the back is largely thanks to Deano, imo. Unfortunately, it's not a quality that you can see reflected in stats because it's more of psychological effect. But watching the games it's really obvious how much more willing willing Maguire and Lindelof have been to play on the front foot, and that impetus has percolated up through the team.
Even if DDG remains the better shot stopper and the more spectacular individual, Henderson should keep the no 1 spot for the sake of team dynamics. I want my goalie to stop attacks before they even happen.
