JIMMY Calderwood has previous for changing games with substitutions.

Rescuing situations apparently beyond repair with a tactical tweak are his speciality, a legacy of years spent in Holland and 
exhibited with Dunfermline and Aberdeen. Yet, even for him, this was impressive.

Before this, Kilmarnock had scored only once in six matches and not at all in their last five league games. At 3-1 down against a team on a run of five wins in six, any hope of recovery appeared forlorn.

Yet the Rugby Park 
players were roused sufficiently to not only restore parity, but to establish an advantage in this tumultuous tie. That they were disappointed that they later let go of that lead is indicative of their remarkable resurgence.

To claim that one personnel change was the reason would be excessive, but the introduction of Conor Sammon was certainly the catalyst. “I’ve been doing that for 10 years,” deadpanned Calderwood of a switch which spooked a United defence riven with susceptibility. “We went to 4-4-2 to get some pace and power up there and it freed wee [Craig] Bryson too. We had to go for it and I think it changed the game.”
