Mounie next turned an inventive header over the bar as a five-man Swansea defence, stationed deep inside their own half by the 30-minute mark, successfully battled their way to the end of a scoreless first half.
The dismissal of their top scorer Jordan Ayew saw the remainder of the game played nearly exclusively in the visitors' half.
"I saw two players try to win the ball with exactly the same movements", he said. They were like two bulls colliding.
Ayew is expected to miss Swansea's quarterfinal game against Tottenham Hotspur in the FA Cup next weekend as well as the game against Southampton.
The Welsh side found themselves down to 10 men with just 11 minutes on the clock when Jordan Ayew received his marching orders for a high challenge on Jonathan Hogg.
His loss for those three games would be a major blow, but Carvalhal is confident his team would find a way to cope. "They're both committing a unsafe tackle so can you give two red cards, you probably can".
"Of course I would rather have Jordan available than not for the next three games", Carvalhal added.
"We got a point because my players showed big character".
"He is a player I like a lot but, if Jordan does not play, we will play with another player".
Carvalhal praised his players and insisted that he was happy with the point they picked as they continue to push away from the drop zone.
