Dan Ashworth.
They've been good for a while, they're just getting better. It's not a popular thing to say in these parts but they were decent under Hodgson and didn't just lump it forward. They've taken another step forward in terms of how they play going forward, and they've got a bit more pace, but they're not radically different to how they've been since getting promoted IMHO.
Be interesting to see how they cope without Ashworth now that he's gone to the FA. Apparently he's helping to find his own successor, although the only name I've seen mentioned is Comolli... Ha.
Summed it up.
When you get an excellent Director of Football with a good scouting network, a good knowledge of the game and good connections, they that's what you get.
They were decent under Di Matteo, but looked like they were heading to relegation around the new year in 2010-11, Hodgson steadied the ship and now Clarke is building upon what Roy did there. Let's see how they replace Ashworth when he leaves his position for the FA at the end of the season.
Saying that, Clarke & Keen have done brilliantly this season, most of the times they have good their tactics spot on and the team lineup and style have always been the right way. Be interesting to see how they do after Xmas though.
