Going by recent history, it looks as if United are shoe ins tomorrow. Six wins from the last seven games against us and just one goal conceded from their last three trips to Paisley suggest that they shouldn't have too much to fear tomorrow. They've also won every time the two teams have met in a cup since we beat them to lift the trophy in 1987. However, there is one thing that gives us a bit of hope, which I'll come onto later - although you can probably guess what it is.
While fans of many clubs will be excited about the prospect of seeing their late transfer window signings in action tomorrow, the same can't be said for Saints supporters. We made just one signing in the last few days before the window slammed shut, and he can't play tomorrow as he's cup tied. Jim Hamilton will have to sit in the stands with injured duo Richard Brittain and Stephen O'Donnell tomorrow, no doubt wincing and groaning at every gilt edged opportunity we miss.
There are likely to be two strikers to miss those chances tomorrow rather than the one we started with against Rangers, with Craig Dargo expected to return to the starting lineup. Chances are he'll come straight in for Garry Brady, with Mark Corcoran and Andy Dorman retaining their places after some decent showings in recent weeks. Gary Mason is suspension free and will probably start, although the decision to drop Hugh Murray - who is most likely to make way - probably won't go down well with some fans. Or we could just play a five man midfield and one striker like we did in December when United came to Paisley - that worked well! Will Haining was sent off last week but will be available tomorrow before starting his suspension.
I mentioned earlier there is something that has given Saints fans a bit of hope ahead of tomorrow. That thing is Barry Robson signing for Celtic. The former Caley Thistle midfielder has played superbly against us in the last few years and the only time he was missing was the only time we managed a win, back in May last year. Him leaving United is great news for us, although they do still have some decent players that could hurt us. Noel Hunt often does well against us, while Lee Wilkie will pose a threat from set pieces.
So, how will it go? Last week aside we've improved, while United have lost their skipper. It should be a closer - and better - game than the one in December, but I reckon United will have enough to sneak through.
