C'mon, you're being incredibly unfair towards Pochettino for not being a native speaker. He can speak English, quite fluently in fact. Of course he's not to a native level of proficiency, but comparing him to Ramos who would notoriously respond "Que?" is extremely cynical on your part.
Highlight reels could easily be made of Mourinho or Wenger butchering English or sounding awkward in their pronunciations, not to mention a great many other foreign managers that have achieved a great deal in the premier league.
I really don't think that there's any question of his ability to articulate basic points. The problems that we've had have gone on long enough I think for most of us to view with skepticism the pretense that there has been something fundamentally wrong with our recent managers at Spurs. For that matter, I really don't think that Pochettino has yet had a sufficient run in order to impose any sort of style or tactics into the squad for anybody to damn him for the lack of attacking intent or authority, etc.
I just think that you're very far out of line.
I do understand the point your making. However, even his employers ( THFC ) have insisted that he speaks English, why would that be ?
I am happy to state that if he had an interpreter and the performances of the team were of a reasonable level, I would not care a hoot how good his English is. However, At the moment we are paying a lot of money to watch absolute shite from the first team and the defence of performances and the follow up comments are not articulated in anyway that is acceptable as, regretfully, the teams spokesman and leader struggles to get his points across. If he can't get his point out in the media, why are we to consider it easier for him to do so on the training pitch or in tactical sessions ?
