Couldn't make the game last night but, from the agonies of following the 'live'

text and others comments, including Professor Coleman, it seems that the problem wasn't the right wing; it was the defence.
As Inspector Morse noted, Clark scored the goal last night and laid on Saturday's winner.
There are options available in defence, so imagine that's where changes will be made.
Midfield changes are more problematic. Scott Brown can be very effective in getting the ball, but he's not the most creative.
Playing an injured Jackson does seem to be a risky strategy. Unless his 'injury' is one that will never improve, I'd rather see him rested so that, when he does play, he's at his best.
