Having finally helped Newcastle avoid relegation to the Championship last weekend, Debuchy believes the experience can benefit the club for the 2013-14 campaign.
"Since January, I have discovered many things and I really have no regrets about coming to Newcastle," said Debuchy.
"When we arrived, me and the other new signings knew that Newcastle were not in a good situation. Yo (Cabaye) explained to me that here, all the matches are tough.
"I've realised that quickly. There was the Europa League, which took a lot of energy, even though we are not going to hide behind that. Physically, it is a big step for the French between the two leagues. You have to be prepared. I felt it from my first matches. It is full-on from the beginning to the end.
"So we knew it would be tough to the end. Well, it has been."
