Kenny Shiels has no regrets about substituting a substitute in Saturday's Clydesdale Bank Premier League game against Aberdeen at Pittodrie - and is surprised that it is not a more common occurrence.
The Kilmarnock boss raised eyebrows by replacing William Gros with Matthew Kennedy five minutes from time - a tactical replacement made only 13 minutes after the French striker had been introduced into the game which ended goalless.
Shiels is puzzled at the fuss his decision has caused and said: "I think it should be normal practice. I don't think it is worth commenting on, I don't think it is a big thing."
He added: "If you bring someone on and you see after 15 minutes that it hasn't had the impact that you had hoped, and you feel the need to change again, then you do that.
"William is strong and quick but he didn't have that impact. I explained to William in the dressing room. He accepted what I said.
"I didn't apologise because I didn't see any reason to apologise. I have done it before. It should be a normal thing.
"As a manager you do what is best for the team and I will never deviate from that. I will always do that. Personalities don't come into it. I have to do what is best for the team on every occasion.
"The decision I made on Saturday was for the best of the team. It could have been anybody, it just happened to be the first substitute who was brought on."
