When you look back at the Villa game at Bramall Lane, Norwood and Fleck absolutely bossed that game and Whelan and the highly rated McGinn, barely got a touch until we declared at 4-0. Fleck was buzzing about and making those driving runs at the defence and Norwood was orchestrating things with his superb passing. Since then, Fleck has been a peripheral figure in a lot of games and Norwood has been nowhere near the standards he set in his first 6 games or so.
I don't think Coutts is ready, he still looked off the pace and his control seems to have deserted him - whether that's because he's still recovering or because he's basically not getting enough game time, I don't know. He was excellent when he came on in the game at Blackburn earlier in the season but appears to have regressed.
Duffy has been getting a lot of criticism lately, but he's still the most likely to create something and what a lot of people seem to miss is how hard he works off the ball. There was a good example on Saturday where he lost the ball a few yards outside their box (to jeers from the Blades fans), Millwall broke away and when the cross came in, it was Duffy who was there at the back post to tidy up. Never goes missing either - always wants the ball, which is invaluable to your team-mates.
