The Sunday Mirror says Manchester United legend Keane spoke only briefly to reporters and became angry when questions focused on the last-minute winner and not a penalty decision given against his side. Iain Hume had missed the second-half spot-kick.
"You've watch the game and nobody's asked me about the bloody penalty," Keane said as he got up to leave. "That about sums you up."
The Irishman then challenged reporters on his way out of the room.
"Was it a penalty? Does anyone in this room think it was a penalty?"
