Fellaini's eight-goal scoring spree from midfield has played a big part in Everton's good form this season, and Spurs defender Kyle Walker knows shackling the Belgian will be key to the visitors' chances of success.
"Marouane Fellaini is a real handful," the England right-back said.
"He's mobile for a big guy, gets the ball down and they go through him. They've good players, lots of internationals and it will be difficult. Ever since I've played in the Premier League, Everton is always one of the tough games.
"But our centre-backs Jan (Vertonghen) and Steven (Caulker) are fantastic and hopefully if we can keep a clean sheet then Jermain (Defoe), Emmanuel Adebayor or Clint (Dempsey) can go and get us a goal.
"If we continue playing how we've been playing and those three keep scoring, then we've got every chance."
