This is all down to the incompetence of Morton, who have spent their time since then at least one division below Saints, although they almost managed to make it back into the same league in 2003/04 before spectacuarly blowing it!
Both teams will be desperate to win this match because it's a derby and a cup semi final, however Morton will be even more desperate as they haven't beaten us since 10th April 1999 (my birthday!) in a 5-1 hammering at Love Street.
The League Challenge Cup has been belittled for most of it's existence, but occasionally it throws up ties like this. I can't wait for it and will be looking forward to our easy passage to the final :-)
