Everton U23s continued their Premier League 2 campaign with a fine 4-1 win against Spurs on Sunday.
The young Blues were ahead after just six minutes. Jonjoe Kenny played a neat one-two with Gethin Jones down the right and whipped over a cross that Niasse powerfully headed home to open the scoring.
A half of few chances saw neither goalkeeper seriously tested as the Toffees were resolute in their bid to hold off a Tottenham side looking for a way back into the game.
The visitors did, however, manage to level just minutes into the second half, as skipper Joe Pritchard saw a deflected strike beat Joel Robles and make it 1-1.
But Everton produced a dazzling six-minute spell that swept aside Spurs and confirmed all three points.
First Ademola Lookman took aim from 25 yards and arrowed a powerful effort into the top corner, before substitute David Henen teed up Niasse for his second.
The Senegalese striker then returned the favour as he slid a pass in for the young Belgian to pick his spot and beat Whiteman to make it four.
The Toffees were then happy to see the game out- although Niasse was denied a hat-trick late on — with the impressive Morgan Feeney marshalling a back four determined not to allow Spurs a glimmer of hope at a comeback.Everton U23s: Robles, Kenny, Foulds (46' Henen), Baningime, Feeney, Gibson, Jones, Charsley (85' Bowler), Niasse, Adenrian (45' Evans), Lookman.
