"My first match went very well, I was pleased to start," Amat told WalesOnline. "It was an important day for myself and the club.
"I really enjoyed being out there. I have a good feeling about this team. It is a dream to play in the Europa League with Swansea City and in the Liberty Stadium. It was an amazing night.
"It was a good result to take out to Sweden, but we still have a job to do - this stage is about two legs, not one match."
The return leg in Malmo takes place tomorrow evening.
