Real Madrid have doubled their efforts to get a replacement, the start player from Tottenham Hotspur Harry Kane is someone they seriously consider above many. If he leaves Tottenham, the new coach Ange Postecoglou who has just agreed to join them from Celtic on a four year deal will have to make his arrangements for a new striker to replace Harry kane of he leaves the club. He will have his options. Tottenham Hotspur as a team need to improve, some more players may be laid off by the new coach as he will want to bring some new players of his choice to the team.
Real Madrid will be easy for looking a new striker because they have a lot money and many player want to join Real Madrid, but Tottenham is different because many player want to avoid to join due to curse of no trophy lol. Regardless how good Tottenham is playing and enter champions league for multiple times, they weren't able to win any trophy like Carabao or FA cup.
Tottenham will become a mediocre club after Harry Kane leaving.
Of course, especially next season when Tottenham do not play in the UCL, it will definitely be very difficult for them to recruit star players.
Harry Kane is the most influential player in the Tottenham team, if he leaves the team then it is likely that there will be a significant decrease in the team's performance.
On the other hand, Real Madrid really needs a front striker this season, Harry Kane is indeed very suitable to fill the void in Real Madrid's front line to replace Benzema.
