Leeds ended their mini tour with two wins and a draw thanks to Paul Huntington's equaliser against Shelbourne, and are unbeaten in four pre-season matches.
McAllister said: "He arrived a few days ago and he'd been training on his own. He can be pleased. He did well. I thought he showed enough, and we'll look forward to seeing him again at Barnet. It was a good test. It was very competitive and I was pleased none of the players reacted. The three games here in Ireland have been a good work-out for us."
