The match started very evenly but where Senegal had the most and best scoring chances.
Ismaila Sarr a great position on a bouncing ball close to Jordan Pickford after just over 20 minutes of play.
Sarr tried to lift the ball high into the net but didn't have his sights set correctly at all.
A few minutes later, it was Boulaye Dia who was played down the left of the penalty area, but his hard shot towards the far post was stopped by a one-handed Pickford save.
But when Senegal didn't capitalize on their chances, England did instead.
In the 38th minute, England came forward in style, putting Jude Bellingham in a perfect position to assist Jordan Henderson for an easy 1-0 goal.
- Not directly deserved in this situation, but the best attack in the match resulted in a goal, said SVT's expert Glenn Strömberg.
Extended just before half time
19-year-old Bellingham wasn't done.
In stoppage time, he won the ball in his own half, broke free and passed to Phil Foden, who set Harry Kane free.
And England's great scorer distinctly shot in 2-0 for an English iron grip on the round of 16.
The goal was Kane's first of this World Cup and his 52nd in the England shirt.
Now he is one goal behind Wayne Rooney as England's top scorer in the national team.
The youth of England continued to assert themselves.
Phil Foden, 22, came loose along the left wing and played in for Bukayo Saka, 21, who coolly lifted the ball in front of goal to make it 3-0.
There were no more goals and England's advancement means that they have to face France in the quarter-finals on December 10.
