I've not been impressed by him at all this season.
Morgan is largely defending well. He's positioning is good and he blocks and challenges well. Moore looks the part but actually makes some pretty poor decisions every game. When there is a gap between the centre backs, it's because of him. His marking at set pieces is terrible. He could easily have been sent off twice too. He does do some excellent things in matches, but he's also still got loads to learn and isn't adapting well enough so far this season.
There is no doubt that Moore lept forward as a player at the start of last season. However, he's not kicked on again since. I'd love him to, but I really don't see him as a top class player in the making.
Young English players are only available at a significant premium for the top clubs. I think Southampton exploited this magnificently. Our squad is already substantially English and so we can do the same. Sell high and replace for less with better.
