The Frenchman remained at St James' Park despite interest from several clubs.
The Frenchman is thought to have attracted the interest of several clubs over the past few months but had his move vetoed, as he confirmed himself in an interview with France Football.
The 26-year old remains committed nonetheless and his words will be encouraging for the Newcastle faithful.
“I’m very happy here,” said Sissoko. “I’m very happy with the players, the staff – everybody.
“When I’m on the pitch I try to do my best. I was fit to play (against Arsenal), and I tried to do my best for the team.
“That is my job. I’m still here. I have four years left on my contract. I will work hard for this team,” he added.
Sissoko has been a key component in the Magpies midfield since his arrival in 2013, but has suffered from inconsistent spells throughout his time on Tyneside.
The midfield powerhouse has all the tools to be among the Premier League’s top performers, yet has been guilty of complacency in the past.
His importance to Newcastle should not be understated, however, and his latest comments will be a boost for the Magpies squad.
A midfield trio of Sissoko, Jack Colback and Georginio Wijnaldum has an enviable balance of aggression and technical ability, and with Vurnon Anita and Cheick Tiote also in contention, Steve McClaren’s team look well-stocked in the centre of the pitch.
