It has been reported that Nagelsmann (his camp) specifically reached out to Spurs.
The social stuff to be honest is just BS, with fans and media alike jumping through hoops to make sense of a cryptic message.
I do appreciate there are very different routes for contact between Poch and Spurs, he remains in contact with Levy, they literally live a 10 min walk from each other (when not in their foreign villas). If you recall Poch's 50th birthday party his house was rammed with current Spurs personnel from his brother-in-law to the PR dept to the grounds staff, so there is very close contact between them that already exists.
The notion that because we haven't made contact with him shows there is no plan is totally bogus. I don't know what our plan is, I do know that we plan 100% not to appoint Poch as our manager. This decision has already been made.
