Not sure where to mention this but The Sunday Times has an excellent (IMO) interview with Eric Dier published today. Its a paywall site so I can't post a link on the News Forum. Anyway it includes this issue with regard to Mourinho. A couple of quotes:
"Dier did not need this interview to convince anybody at Tottenham about his bond with his boss, but he would like anxious fans to hear. Hear how, despite a difficult situation last winter, "my relationship with the manager has become even stronger for what we went through"."
The article talks about Pochs book and the timing, etc. Dier is also quoted as saying:
"I've always been so happy at Tottenham. There have been moments like January (the Mourinho thing) built out of frustration but never a period where I wan't happy. I say it to friends and family, that I think its very difficult to be in a group like we have here where - and every single word of this is honest - I don't have a single problem with one player in the dressing room. And that's true of the whole team. We really connect as individuals. It's something special because it happens so rarely in football and that's one of the reasons why I've never thought of leaving."
He admits to loss of form after playing 61 games in 2015/16 culminating in the Euros with England, and tiredness.
He talks also about his preferred position.
All good stuff. Very reassuring.
