The Swiss centre-back signed for the 'Magpies' from Deportivo, and he can't wait to get started in the north east.
"The Premier League is the best league in the world, you have so many good players and many good teams. Almost everybody can beat everybody so that is what I am looking forward to," he said to 'Sky Sports'.
"With the great stadiums and all the fans, it's going to be fantastic next season. I'm really happy to be here. England is the best league in the world.
"I need some training and some more pre-season because the season is coming quick, and I have to be ready in maybe just two weeks. I'm really looking forward to it.
"I have had maybe two or three training sessions with team-mates, and one game, so I need some time but what I have seen is that we have a good team and quality in the squad."
