Indeed, the 61-year-old says the Frenchman should hope he has a 'huge contract financially' as the amount of games he has played and subsequent lack of success so far at St James' Park haven't justified his decision to leave Ligue 1.
Courbis feels Cabella can't be truly happy waking up to go and train at Newcastle every day.
He is quoted as saying by the Chronicle: "With some irony, I said that I was not mad about Newcastle (as a choice of destination).
"I sincerely hope with all my heart, because God knows I love this little boy, that he has a huge contract financially. From being with Montpellier and being in the 23 players that represent the France team, to going to playing only a part of the games, while scoring one goal when you scored 15 or so with Montpellier [per season], I really hope he has some financial compensation.
"If in the morning, he wakes up and he is happy to go to train at Newcastle, he will have to question himself."
Cabella was recently backed heavily by supporters after posting a picture on Instagram and confirming he had returned to Newcastle's training centre after surgery.
Apart from a select few, the general consensus among the Magpies faithful appears to be that of being positive and backing the Frenchman to produce a much better return during his second season at St James' Park.
The 25-year-old flattered to deceive during his first Newcastle campaign but could there be improvement under new boss Steve McClaren?
Cabella will no doubt have to up his game considering the added competition at the Magpies after their summer recruitment. The chance could be there, though.
