The France international became the latest United recruit when he completed his move from Toulouse and signed a six-and-a-half year contract at St James' Park. His initial mission, along with fellow new boys and compatriots Mathieu Debuchy, Mapou Yanga-Mbiwa, Yoan Gouffran and Massadio Haidara, will be to ease the Magpies out of Barclays Premier League trouble.
However, Sissoko had much loftier aims in mind when he put pen to paper. He said: "My personal objectives really are to finish off this season as best as we possibly can. I am going to give everything I can so Newcastle finish as high up the league as possible. For the future, I want Newcastle to be one of the very best teams in the Premier League."
He added: "I have signed here because I love the club. They have some fantastic players.
"Newcastle aren't in the position where they should be at the moment, but I think if we all do well, we will finish as high as possible and really make the team one of the best in England."
Sissoko's arrival means Newcastle now have 12 Frenchmen on the books - The Strawberry, the nearest pub to St James', has been re-named La Fraise in their honour - with the club sticking to its policy of trying to find the best value possible for its money.
However, Sissoko in particular landed on Tyneside with a reputation - he has been dubbed in certain circles as the new Patrick Vieira - and he did so confident that he can enhance his standing both at home and abroad and maintain his place in the France squad.
He said: "I hope so. Here in England and particularly at Newcastle, everything is in place for me so I can really do well.
"As you say in England, I am a box-to-box player. I like to go from one box to the other. I like to get myself forward and attack - Newcastle have signed me for that reason, and I must use that to help out the club.
"I think my style of play is really suited to the English game. It's now up to me to go out and prove it in each and every match on the pitch. If I do that, then I will definitely, in my opinion, be rewarded by continued appearances with the French team."
