At this time, Postecoglou drew attention when he put Son Heung-min as a front-line striker rather than a left winger.
Towards the end of the summer transfer market, Tottenham tried to fill Kane's vacancy through Brazilian striker Hisalisson when world-class striker Harry Kane, who was in ninth place until last season, moved to German Bundesliga champion Bayern Munich.
However, when Hishalisson failed to show much impact at the front line, manager Postecoglou boldly put Son Heung-min as the ninth striker in the match against Burnley. Son Heung-min's existing position was played by Israeli winger Manor Solomon.
Postecoglou's choice was a huge success. In the match against Burnley, Son Heung-min scored as many as three goals, including his first goal of the season, leading Tottenham to a 5-2 victory. It is Son's fifth hat trick since he entered Tottenham in 2015. Last year, he scored three goals as a substitute against Leicester City in September.
Tottenham, which has seen the effect of Son Heung-min, the "No. 9 striker," placed Son Heung-min at the front line in the sixth round of the league against Arsenal and the 194th "North London Derby" on the 24th of last month. Son Heung-min once again lived up to the coach's expectations by scoring two goals against Tottenham's biggest rival. Thanks to Son's performance, Tottenham ended up with a 2-2 draw against Arsenal on the road.
Son Heung-min's Arsenal performance was highly regarded, and Son Heung-min was the first player to score two goals in Arsenal's away match since the Premier League was launched in 1992. Tottenham legends Harry Kane and Gareth Bale also failed to score more than two goals at the Emirates Stadium, which Son Heung-min did.
Son Heung-min, who played full-score until the match against Arsenal after Burnley, continued his momentum and scored the first goal at home against Liverpool in the seventh round of the league on the 1st to help them win 2-1. Liverpool scored his sixth league goal by pushing Hishalisson's cutback into the goal, aiming for a numerical inferiority.
