"I think that this league is made for me," Sissoko told reporters on Monday. "I had the desire to play in the English league and Newcastle gave me this opportunity. I am very happy to be here."
Sissoko enjoyed victory over Aston Villa on his full debut but admitted he could not have hoped for a more successful bow on home turf.
The 23-year-old hopes to continue to contribute as an attacking force having been given more license to roam under his new manager.
"I never would have imagined that," he reflected. "First home game, against European champions Chelsea... if I had been told I would score two goals I would not have believed it.
"My game is forward-driven. At Newcastle and in England football is more offensive so it suits me better."
