Spurs have got things rolling in the attacking side of things, even though they lost their best player and record goalscorer in Harry Kane. They have now successfully, for the first time in Premier League era, scored consecutively in 33 games. Credit goes to their manager Ange, who's philosophy works really well in the EPL. Attacking football.
I guess even with Harry Kane, Spurs weren't doing this well offensively. The biggest factor is Son, he includes himself in positions in all matches, throws or makes others throw. Then RicharlisonComing in, he is also a good centre-forward, he is quite adequate without Harry Kane and he has done a good job so far. They are on the same points with Arsenal, they are in a good position to stay in the top four, and they have the image to achieve this for now.
