Tottenham chairman Daniel Levy is rethinking a move for Julian Nagelsmann.
Levy was planning to make the former Bayern Munich coach his new long-term manager after Antonio Conte's departure last month.
But the Spurs chairman is now rethinking is plans.
Levy has concerns about the 35 year-old being too close to the age of his players and so lacking in authority.
However, The Sun says it isn't thought to be a dealbreaker.
Meanwhile, Nagelsmann is not demanding full control of transfers if he takes charge - contrary to English press reports.
