"He missed a penalty (and I was surprised when it was given) but I thought Juan was great for us," said O'Leary after the game.
"There is a lot of disappointment all-round in the way we played as a team. We can play a lot better but his work-rate and effort was second to none.
"It's a pity he didn't score the penalty because it would have been well deserved.
"He was our best player by a mile. It was a wonderful goal."
