Alan Pardew's side took until late April to confirm their Premier League status for another campaign, with the likes of captain Fabricio Coloccini, Chiekh Tiote, Tim Krul and Cabaye himself all hit by injury throughout.
The France international notes that Europa League committments could well have contributed to Newcastle's poor domestic form, but is still keen to kick on next term.

"We had a lot of injuries to players as well, with big players missing, and that was hard when we were playing in the Premier League and the Europa League.
"But we fought together and stayed together and we fought to be a Premier League squad next season which is the most important thing, I think.
"We have to learn about our mistakes but the main thing was safety and the club staying in the Premier League. So it was a hard and difficult season but I think for the future, it's going to be interesting because we learnt a lot."
Newcastle bolstered their ailing squad with five new additions in January - Moussa Sissoko, Mapou Yanga-Mbiwa, Massadio Haidara, Mathieu Debuchy and Yoan Gouffran - and Cabaye feels the quintet will all see an improvement to their performances following a full pre-season with the club.
"The new players who came in January are going to have more time to adapt to the Premier League style, he added.
"Hopefully we're going to have some time to prepare well for next season and to be fit for a big part of the season, because that's going to be important to play for a place near the top of the league."
