To find a striker of Kane caliber is very difficult, we can mention a name like Osimhen. We also understand that the competition to get the signature of a player like Osimhen is also very difficult, not just money but also the club bargaining value in winning trophies.
A player as badly out of form as Werner is unlikely to help Tottenham. The mockery Tottenham are getting for the loan is justified. There are some up-and-coming top strikers in Europe's smaller leagues who have a good goalscoring quota this year. If Tottenham had spent 20-30 million and signed such a player, they would certainly have profited more. Now it remains to be seen and hoped that Werner, against all expectations, performs in a good way.
But Tottenham have reasons for choosing Werner even though their performance is not so good, the most reasonable reason is because Werner plays more often in the top European leagues, but Tottenham also still has hope where Werner can return to his best performance.
Newcomer top strikers are sometimes doubted, even though the team has to spend 20-30 million their experience is still not much in a tight team when they are not mentally ready then there are only bad performances and more often on the bench.
Ange may choose a more experienced player, and he can groom that player to be better.
