Not sure that's fair; in the main, most days now you can read an entirely positive article/opinion piece about Ange/Spurs here (in the UK that is), whether it's in regard to his long route to top class football/the way we now play, or the way he answers questions with humility and honesty (a highly unusual trait in PL managership)...
As a generalisation, I think the press see him as a breath of fresh air as opposed to the arrogance of two of our previous managers and are loving asking questions about what he thinks, and how he's doing it, as they get open, transparent answers that don't have to be interpreted.
