Yes, I think taking off Cha was a bit premature, though he may have been limping a bit. In fairness, the management weren't afraid to make the changes after the poor first half, and bringing him forward seemed to get everyone on their game more. However, we do seem to have a bare enough panel, overall. A couple of injuries, and where are we? Mind you, Downey did well when he came on - could have earned himself a start next time?
As for Flemming dropping off the panel - looks like he should've stuck around. Bad mistake for Westmeath's second goal, and it was a shame to be in a tight corner after putting up such a big lead.
