Spurs are going crazy and they are still undefeated. Their latest win at home against Fulham provided cold weather at the top of the standings and I think their hope now is of course to be able to get closer to winning the title which every season is very impossible for them. In 9 matches Spurs have never lost and they are the only team left in the EPL that is difficult to beat.
Honestly, when Kean left, I had this idea that Spurs would lose about 50% of their strength, and it'd be challenging for them to stay in the top 4, let alone leading. But I might be wrong because right now, Son and his teammates are playing exceptionally well and consistently. I sense that Spurs' playing style has become more varied compared to Kean's time.
If they play for an Asian team maybe they are willing to be called up to strengthen their country national team.
It is the dream of many players to be able to play with big European team one of which is the Premier League.
Playing for a European club like the Premier League rather than an Asian one is a huge advantage. This will likely make them top choices for their national teams, and if they play well, their country will also be noticed.
