"If I'm being honest, I'd like more of a complete performance," he said. "Possession wise, it wasn't great. We didn't keep the ball as well as we can do. I felt really confident going into the game with a very powerful and strong team, I thought it would be a dominant team. But, unless you keep the ball, you're going to struggle in European football and that's what happened.
"In fairness, we did quite well in the last 15 minutes of the first half and the last 10 minutes of the second half. We took so long to get going in both halves that you're always going to put yourselves under pressure."
One real positive was an excellent performance by Tyrell Warren at right-back with the 16-year-old local lad catching the eye thanks to some tigerish tackling and boundless energy.
"He was probably the best player on the pitch," said Butt. "He defended really well, made some last-ditch challenges and did well against two men coming down the left-hand side for most of the time. He did really well but, overall, it was a disappointing day as I'm a coach who wants to see lads play and be confident by dictating play and we didn't do that at all really."
