Harry Kane was already in his thirties, albeit by less than two weeks, when Thomas Tuchel agreed to pay €100m for him. Bayern Munich have since seen a return in the form of 82 goals in two seasons and if Tuchel need not worry how much resale value the striker has, he only needs to concern himself if Kane can keep going until a World Cup that ends just before his 33rd birthday.
The England captain has looked far further into the future, however. An admirer of Tom Brady, Kane has spoken of a desire to play into his forties. He admires Cristiano Ronaldo for his longevity and, at the age of 40, the Portugal captain has scored in both the Nations League semi-final and final in the last week. Can Kane follow in his footsteps? Tuchel believes it will not be easy. Ronaldo is an anomaly in many respects. His age is one of them.
