Allen told the Western Mail “To start for the first time at the Liberty Stadium, and to win as well, made it a fantastic night for me,” said Allen.
“It does not get that much better. It was a thrill.
“I’ve missed out on a few squads in the past and it is about making up for lost time.
“You’ve always got to be disappointed when you don’t play or you don’t start the game. I’ve always been the same.
“To be an international regular has always been my aim but it’s a massive task, both for Wales and at club level.
“But it’s a target I’m striving to achieve. We have a lot of very good players in the Welsh squad, so it’s a case of always working hard and enjoying what I am doing.
“It’s early days for me because it was only my fourth cap and my first start.
“Nothing changes from my point of view. I enjoy coming away and I will work hard every day in training and see what happens from there.”
