He continued: "We lacked concentration sometimes tonight and it proved costly. They broke quickly and we were a bit slack. We know we need to improve at the back. Hamilton Accies won the league last season not on the basis of the goals they scored but on the goals they didn't concede and we have to get things tighter."
Clarets boss Owen Coyle said of the game: "For the first twenty minutes I thought we looked very slick and controlled in our play and generally looked a very good team. I was disappointed with the goal we conceded and from then I thought we lost our way a little for ten to fifteen minutes.
"We scored a very good second goal and the second half was probably very similar to many of our re-season games in terms of changes. When you make so many there is not much in terms of fluency, but I am very pleased again especially with the fitness levels.
"We had to work hard because you can see St. Johnstone are a very good footballing side, so overall I was pleased with the finish."
Coyle said that Kevin McDonald was left out as a precaution with a foot injury and also added that Remco van der Schaaf could feature at Accrington. He also said a decision would be made on Gatis Kalnins within 24 hours.
He also had both praise and a warning for new striker Martin Paterson. Coyle said of his £1.3 million capture: "Martin is 21-years-old, he scored fifteen goals last year in a relegated team and he is a Northern Ireland international.
"We certainly feel he is only going to be better, but I have given him a rollocking in there. He is a young player who we have high hopes for and that's why we invested the money we did. But whether you think a decision is right or wrong, you cannot be involved in any sort of back chat.
"He is a young kid and he wants to do his best, so he has learned his lesson. It was an important lesson, so it is probably good that it came in pre-season."
