Kilmarnock manager Neil McCann: "I didn't find it entertaining whatsoever. We got exactly what we deserved from the game - nothing.
"Can't defend like that, can't play like that and expect to win a game of football. That said, we're 3-2 up.
"The third goal they get... we need to do miles better from the set piece, and we'll look at it, but it's never a free-kick. Jamie Brandon has won the ball quite cleanly and John Beaton [the referee] somehow manages to give a free-kick. I've asked him why, he said he thinks it's a free-kick. I disagree.
"The video evidence shows Jamie does get a touch on the ball and we are severely punished. We have to then do better with the set piece.
"The fourth goal is just ridiculous. We're miles better than what we showed today and it's a stark reality of what the Premiership is like. St Johnstone deserved to win today, simple as that.
"I don't think our performance today merited anything. The Kilmarnock fans deserve much more today. We didn't start the game, and from the off they looked like they wanted to celebrate being back in the Premiership.
"The first time we played, we scored. I tried to adjust a few things at half time, but it's one of those early games in the season when no one is at top gear, but we need to be miles better."
