Kane scored a hat-trick to take him to five goals for the tournament, one ahead of Cristiano Ronaldo and Romelu Lukaku in the race for the Golden Boot.
“You have to believe,” Kane told the BBC when asked if England can go all the way and lift the trophy. “There is a long way to go, a lot of hard work but we just have to stick to our game plan.”
England have scored five of their eight goals from set pieces and Kane says it’s testament to the hard work that goes on in training.
“We have been working on set pieces and working on the way we play and it is all coming together. (It’s) fantastic to be through and to do it this way is brilliant.
“I am so, so proud of the boys,” the captain added. “The fans have been brilliant, both sets of fans to be fair, that is what the World Cup is about. We are enjoying it and we have to keep it going, not get ahead of ourselves."
"We got to go into the game against Belgium looking to win but this win gives us a bit of a cushion. We will see what happens."
Ruben Loftus-Cheek made his full competitive debut and played tribute to England’s ‘respected’ young captain. “For such a young captain Harry Kane is so vocal and I think everyone respects him massively in the team," he said.
England face Belgium in their final Group G match which will determine which side qualifies as group winners. Finishing second provides a slightly easier run in the tournament as it could avoid Germany or Brazil in the quarter-finals, but Kane is confident England will win their third World Cup match in a row.
"We got to go into the game against Belgium looking to win but this win gives us a bit of a cushion,” Kane said. “We will see what happens."
