I'm trying to think back, but this must be our biggest league game for absolutely ages.
I'm talking about in terms of it being a big game for both sides, for the same aim (CL in this case) with the significant reward for the winner being that much more attainable.
There was the Utd game in 04/05 when Dunc scored but they were marooned in 3rd by then with nowhere to go.
Individual games have been big like the one at the end of 04/05 against Newcastle etc
Different rewards but I think we're going back to maybe some games in the run ins when we've been fighting relegation - against Charlton in 98/99 (part of Super Kev's run)?
At the top end of the table we're probably looking at mid 80's derbies (although the top end is bound to be tougher as no extended CL places meant that rewards were miles off if you were 6th/7th with about 8 games to go).
