Is Michael McGovern in there? The save Stockers made to nudge the header on to the bar v Villa was pretty special imho.
That's another of his strengths on top of distribution, reflexes where shots or headers are close to him. It's his footwork that appears all at sea. His trigger movements and weight distribution seem wrong to me hence being beaten too easily by distance headers.
Hopefully Ben Roberts who was a superb keeper can iron out these flaws.
