Nagelsmann was managing Leipzig before joining Bayern Munich as you know. Therefore I don't think Tottenham is much of a recession for him.

He wouldn't like to return to an average team again after this big step forward I guess. Tottenham would be another nice option to go for. Maybe Tottenham aren't a team that has a history full of titles. But still they are a really strong team now considering their players in the squad. Kane is their biggest card above all else. But Kane might also think of leaving also after having another season without a title. I don't know if Nagelsmann would be the manager to make Kane think twice about that.
