Asked whether he thought his side did enough to win the game, Di Matteo replied: "I think so, we had plenty of chances.
"Their goalkeeper made some very fine saves to keep them in it.
"You kind of hope that the substitute keeper is not that good but he had a hell of an afternoon.
"But we've got to take the chances, absolutely. If you create them and get in those positions you just need to score. That's how you win games.
"I thought we were quite solid, we didn't concede much to Newcastle, who are a very good team with quality players.
"It was a tough afternoon but I think we did well."
