Chelsea take on Spurs at White Hart Lane tomorrow evening, with the aim of maintaining their three point lead at the top of the Premier League.
And Merse is confident Jose Mourinho's men will begin 2015 with a bang.
"Chelsea will win 3-0 - and I'm being kind to Tottenham here, as Chelsea fans call it 'Three-point Lane!'," he told Sky Sports.
"If Man Utd were as ruthless as Chelsea are then it would have been 3-0 on Sunday.
"It is only waiting to happen at Tottenham, believe me, they are waiting to be on the end of something big and I think this will be it.
"I think that Chelsea are head and shoulders above Tottenham and the game will be over in quick time."
