Don't believe a word of it. There are a number of issues at play here.
Firstly, some journalists have no love for 'new look' Spurs. Our manager (and chairman) make a point of not playing to the media. Mauricio Pochettino gives them nothing and laughs at them as he does it. When 'Arry was manager, things were a bit more triffick. 'Arry would say that so-and-so was a "great player", "triffick family man" but he was at another club and he couldn't discuss him (having just done so.) New Spurs give no headlines or stories, the journo's hate it and just say anything they want. Kyle Walker apart, none of this comes up at press conferences.
Just as Real Madrid have Marca to do their dirty work, so United and Chelsea have journalists and newspapers that will run stories for them. The Kyle Walker to Chelsea story came from The Standard. The Sun will do anything for United.
Do United want those players? Yes, they do but nearly as much they want Spurs weakened. Mourinho doesn't fancy going toe to toe with Mauricio Pochettino as he has done so at Chelsea and Madrid and knows he is a considerable opponent and United can't keep winning the EL. Next season he needs Top 4 and he needs to weaken his opponents. Our financial position makes us first pick. Arsenal will be next as United bid for Sanchez and Ozil and Coutinho to Barcelona stories ramp up.
If Spurs turn down any bids and talk to the players about the career successes that moving there has brought to Pogba, Martial, Shaw, Schneiderlin, Depay, Di Maria...........then how we'll be renegotiating once we're in the new stadium and Mauricio Pochettino is staying and it's a World Cup year in 2018, this all goes away.
I'm sure that the trip to Hong Kong is going to remind the players what they are a part of. Mauricio Pochettino has come out and committed to the club's future in the new stadium. There's no chance of this coming to pass and I don't think anyone involved has any expectation that it will. Not Spurs, United, Mauricio Pochettino, Jose Mourinho or the journalist that wrote it.
