Son Heung-min and Harry Kane combined again as they scored for Premier League leader Tottenham in a 2-0 victory over Arsenal in the north London derby on Sunday. It was a wonder goal from Son that put Spurs in front in the 13th minute. Freed down the left by Kane, the South Korean cut inside and curled a brilliant 25-metre strike into the top corner. Son returned the favour, teeing up Kane to smash in from close range off the underside of the crossbar in first-half stoppage time as Tottenham returned to first place. Son and Kane have now combined for 11 goals this season. “Harry and Sonny are world-class players and, on the top of what they do, they have a very good sense of the team,” Tottenham manager Jose Mourinho said. “They have a very good sense of the balance that they need and they also do incredible tactical work for the team when the team doesn’t have the ball. So top players, amazing.” While Tottenham is unbeaten in 10 games since an opening-day loss, Arsenal has lost six times and is 11 points behind the leaders in 15th place. “We need to score goals. It is not sustainable,” Arsenal manager Mikel Arteta said as the club endured its worst league start since 1981. “It doesn’t matter what we do in other departments if we don’t score. We need to put the ball into the net urgently. At the moment it looks like we need a lot to score a goal. “In terms of the performance, they did everything that I asked them to do. We played the way we had to play this game. "All the stats are in our favour. At the end of the day it is about putting the ball in the back of the net.” The win came in front of the first crowd allowed at Tottenham’s stadium since March, with the 2,000 tickets restricted to home fans because of continuing pandemic restrictions.
