Tottenham beat rivals Arsenal 1-0 at Wembley on Saturday to move back into the top four of the Premier League, while also extending their lead over Arsene Wenger's team to seven points in the race for Champions League qualification.
The victory lifts Mauricio Pochettino's side into third place in the table, having played a game more than Liverpool and Chelsea, while Arsenal slip to six points adrift of the coveted Champions League spots. "We contained them to very little", Wenger said after the game.
"The game should have been finished at half-time for me".
After a sluggish first half, Kane jumped highest to head home his seventh derby goal in seven games and Spurs would have won by a greater margin but for an inspired performance from goalkeeper Petr Cech.
He added: "That doesn't work - we have to play much better away from home and make superior results if we want to have a chance to come back".
"Watching the last few games, we are comfortable in the way we are playing and the shape we use [4-2-3-1]".
Arsenal return to the field for a Europa League last 32 first leg against Ostersund on Thursday, with the second leg set for the Emirates Stadium one week later.
Arsenal's record of just 4 wins out of 14 games on the road is probably one of the worst I have ever known, and Wenger thinks this is simply down to our strikers not converting the chances they get. We didn't create chances, we didn't have the ball like we should have done and then in the second half we paid for it.
"For many years the one thing Arsenal fans could comfort themselves with when they were not winning trophies was the fact they are top dogs in north London, but that is no longer the case now. We will be ready to be very competitive".
"It is too hard to know", Pochettino said.
On the other hand, the hosts will depend on the harmony between their attacking line players, Christian Eriksen, Son Heung-min, Dele Alli and Harry Kane who tops the Premier League goal scorer list with 22 goals. "If it is an opportunity we have to try to take it as well, but the priority remains the Premier League".
The England worldwide has won back-to-back Premier League Golden Boots and is on track to better his tallies of previous campaigns.
