The former Lille star joined the Toon on Friday.
The 25-year-old midfielder believes the future is bright on Tyneside and is confident that reinforcements will help the team achieve their targets.
He said in the Daily Express: "I am going to play in the best championship in the world for a club who want to get back into Europe within a year and one who are building an ambitious team.
"I am the first recruit but I have discussed things with manager Alan Pardew and I know others will follow. The directors have assured me on this point."
