For me as a Manchester based Sky Blues vs it's a relatively easy double header few days.
Blackburn experiences , real lows and highs there. 1980 cup defeat and a thumping 4-0 away match defeat. A real highs of 5-2 win in early 90's and fa cup win in late 90s in Huckerby and Whelan era. I took I've seen another defeat there too.
Preston , all bad memories. Desperate, humiliating and promotion ending 2002 4-0 defeat after travelling down from Edinburgh. Chris Hussey dreadful last minute defending in a late unnecessary loss. Attending in a 1-1 purely to protest about SISU and being in a very divided toxic away crowd. Being outside Deepdale last year behind closed doors before game which ended up a defeat.
No chance of winning at Preston, I can dream but highly unlikely. I hope the fans are well behaved at Blackburn and celebrate at least a draw. Gosh that 5-2 win game was one of the best away wins ever.
