The defender told Sky Sports News: "I think we need to play through the middle a bit more and pass the ball to create chances for us to go forward more.
"Of course, I am allowed to go forward but I don't think we get in enough positions to get ourselves forward. The lads were absolutely devastated after the game.
"First half, I thought we played all right. Second half, I don't think we played well enough to get a result from the game. We know we have got to go to Austria now and get the win."
Ireland face Austria in Vienna on Tuesday.
