Of course, if Tottenham are able to defend consistently in every match this season then Harry Kane departure will not have a big impact on them. Apart from that I think a big impact is starting to be seen in their front line because Richarlison was not in his best form at the start of the season because he was Ange Postecoglou main choice but his performance was far from expectations. Richarlison has played 4 matches at the start of this season but he failed to contribute through goals or assists.
So, little by little, Tottenham will feel like they have lost their goal machine, Harry Kane. However, Son brilliant performance has made Tottenham run at the start of this season look perfect. I'm sure they will improve in the winter transfer window to strengthen their attack line.
Tottenham's current attack is surely having big impact in early matches of this season without legendary Harry Kane as they are having 11 goals from 4 matches which is impressive with their main striker is still not in good form which can make things better for them in coming matches, and we can expect good result from them which could be surely surprising because currently this all is beyond expectations of soccer community which was feeling Harry Kane lost can bring negative impact on this club.
Son and Maddison surely doing good with good support from Romero and other players making things better without any doubt if we have same level until winter then we can expect one of the best fight for the top fours in this season in Premier League.
