Hard to know isn't it where the line might be? I had Villa down for EL progression, and yes they may well do with Emery and a rested first team, but IF Forest get a result in the second leg and what seemed almost certainly like a bunch of places for grabs will suddenly be one less.
With a bit of a points gap already, plus our fairly poor goal difference, just feels like we'd need three wins to me as the form of the teams above us is generally decent/good.
EDIT: I suppose the Villa thing would only mean the CL places would reduce and switch to EL. Can't keep track
