Two late goals gave the promotion chasing West Brom victory at the Liberty with a late penalty sparking the drama and controversy.
Speaking after the game, Di Matteo said "The most important thing for us tonight was getting something out of the game
"We're very pleased we managed to win.
"The game more or less went the way I thought it would.
"Swansea don't concede many goals but, on the other hand, they don't score many either, so we knew there wouldn't be many chances.
"We knew we had to stay in the game for as long as possible because we will always create a chance.
"The 0-0 scoreline was good and the longer the game went on with that scoreline, the more I thought our chances of winning would increase.
"It was a very mature performance.
"We didn't give much away and took our chances when they came along.
"If we don't concede, we've always got a chance of winning games as we've scored in every match in 2010.
"It was a great result as Swansea is a difficult place to go.
"It was a clear penalty," he added.
"There's no discussion about it.
"Giles put the ball past their defender. Their defender then stuck his leg out and cut Giles down.
"If Swansea are upset about it, there's nothing I can do.
"Dozza is very cool and composed on penalties and his goal was vital for us.
"Tonight the substitutes definitely had an impact on the game," he reflected.
"We haven't had them for most of the season so we're glad they are coming back into the team and are able to help us in trying to reach our target.
"We know Ishmael's qualities and we've got to get him to a stage where he can start and finish games.
"But it's a balancing act at the moment."
