Much credit to Wilder for this--another example of an open-minded, self-reflective and humble but decisive management style that is happy to acknowledge misjudgements or mistakes and correct them accordingly, or to try other things. (Other examples include rapid changes of heart on Hussey, Long, Coutts, Freeman, etc).
Duffy started off in the side as, and presumably was scouted and bought in as, a winger, but brought very little to the team in that position, early doors. Acknowledging this and shifting him inside, then allowing him to drift in a no.10(ish) role, has been one of the keys to our great run. Left out wide and consistently playing below par, by now he'd either be a regular on the bench or spending every other Saturday sitting in the block behind the dug-out in a shiny suit.
As much noted, he's so hard to defend against partly because he constantly sees, then moves into, space. This is not an easy thing to do in a 5-man midfield, where space can be limited, particularly when our 5 is matched by the oppo as has happened several times already this season, home and away. His ability to do this also gives us a fantastic, and always potentially destructive, asset against park-the-bus visitors.
It looked to me, though I was a bit bleary eyed, like Oldham set up to man-mark him, and did so quite effectively in the first half. One reason, I think (alongside a below par rest of the midfield) why we looked a bit ropey on Boxing Day ? Most encouragingly, tho, even man-marking him wasn't enough, in the end, to stop him decisively influencing the game.
Smart !
