I imagine the board have a list of candidates for next season. Some would only be available if we stay up though. Im sure NA is just a interim replacement. Lennon and Bielsa would only come if we stayed up. If not the likes of Mackay and Sherwood are more likely.
I'm sure McNally is viewing the Fulham game as the season decider, win that we will in all likelihood stay up, lose and we will almost certainly be relegated.
If he wins then has the expected results against the big four he can still get rid of him. If he wins another and gets a draw then it might be a tricky decision.
yeah that's how I read it after I'd posted! It was originally in capitals, but this annoying site...
