Rangnick told Sport: "Bayern should have signed Harry Kane at 20. You have to sign a Harry Kane at 18 or 20 and then keep him as long as possible. That would be my approach. But I repeat: every club has to decide for itself. You have to make an effort to discover this type of player earlier.
"He scored a lot of goals, won the league, and had a positive influence on the atmosphere in the dressing room. Yes, they won the German championship, which is logical for Bayern. But they didn't win the cup. They didn't win the Champions League. We'll have to wait and see what happens in the next two years. I'm not saying it wasn't a good signing, but my approach would be different."
