"When you come to places like Everton who will play long balls into the box you need big, strong defenders, but we won't use injuries as an excuse," he added. "I thought the players who came in gave their best and hopefully we'll have a couple of defenders ready for the next game.
"Towards the end of the game Everton looked a bit tired and I believed, even up until the last minute, we would score because we had some good possession and they sat back a bit. Unfortunately we just couldn't get the goal."
