Dunne has impressed for Villa since joining the club from Manchester City this summer and has already scored twice.
But Dunne insists he is impressed by Collins.
“He’s been outstanding since he has come in. Every game has been brilliant,” Dunne said.
“In this game [Chelsea], he really topped it off. Any ball that came in the box, he headed out and on the ground, he dived in front of it.
“Then for him to get the winner was really good. I think he is really enjoying himself, as am I.
“It’s going well and it’s nice that we can score goals. The important thing is keeping them out, but for him to get the winner is also nice.”
