The Frenchman was delighted to get off the mark for his new club as the Parisiens breezed to a 4-0 first-leg win at the BayArena on Tuesday
Laurent Blanc's side strode towards the Champions League quarter-finals by thrashing Sami Hyypia's men, with Zlatan Ibrahimovic netting twice after Blaise Matuidi opened the scoring early on.
Former Newcastle man Cabaye, who added a fourth with his first goal for the club at the BayArena in the dying minutes, says his team-mates were a pleasure watch from the bench prior to his introduction.
"I'm very happy. It was a great evening. I'm adapting more and more and I'm full of confidence on the pitch," he told Le Figaro.
"Qualification is amost assured but we have to play very seriously for 90 minutes at the Parc des Princes in the return leg.
"It's a match I wouldn't describe as perfect, but almost perfect. Everyone was at their top level. It was a great first half, we were truly extraordinary. I got a lot of pleasure from watching this team play from the match."
Cabaye went on to voice his hope that scoring will help ease his adaptation to his new surroundings follow his January move from St James' Park.
"I think that the goal will liberate me because it's never easy to arrive at a team in January," the former Lille man added.
"Even though I've returned to Ligue 1, a league I know well, you have to adapt with new team-mates and make an effort to get a place in the team."
