Houston delighted at late goals
Peter Houston was not surprisingly pleased at the contributions of his substitutes in the 2-0 win at Inverness Caledonian Thistle on Tuesday night.
Midfielders Prince Buaben and David Robertson both found the target following their introduction as the visitors swapped places in the table with their latest hosts.
"When you have a guy like Prince Buaben on the bench it is nice to bring him on," Houston told BBC Scotland. "Fortunately he scored. And Davie went on and scored as well. So I think I am a wee bit lucky tonight that the substitutions worked.
"I was wondering where the goal was going to come from," he admitted. "I felt that young Stuart Armstrong, who had a fantastic game, was starting to tire a bit. It was fortunate for me that Prince Buaben goes on and in a couple of minutes he has scored a goal.
"In the same breath you see Danny Swanson getting a bit tired as well and you've got Davie Robertson, who is a good safety guard, and he goes on and scores."
