The Frenchman has been discussing his work-rate and dedication.
Indeed, the 26-year-old has struggled for form for some months now at St James' Park, although he has occasionally shown glimpses during rare Newcastle wins this season.
And the Frenchman has defended his dedication and work-rate, suggesting that has never been an issue for the midfielder.
Sissoko told the Chronicle: "When we win the fans sing my name. If we lose or play badly, they are disappointed with me.
"Every game I try to do my very best. Sometimes it works, sometimes it doesn’t. But I give everything I have."
Judging by Sissoko's performances over the last few months, however, that is a very contentious claim indeed.
During the 6-2 win against Norwich City, Sissoko's attitude was summed up. He was sensational going forward for Newcastle United. But, defensively, he was nowhere to be seen.
If he was like that when the Magpies were winning, imagine how unwilling he has been to work hard when Newcastle were getting hammered on countless occasions?
In truth, the one thing that can be questioned is exactly that: Sissoko's dedication and effort. For every Newcastle fan knows what a talented player he is, it's just that the Frenchman quite blatantly chooses not to show it more often than not.
