I have no allegiance to any premiership teams, other than a slight interest in Spurs because I enjoyed their 60s team as a kid, it it does seem their managers increasingly lower the tone of the debate when they lose.
Guardiola is a great manager, especially when winning, but seemingly scraped the bottom of the barrel when criticising Klopp for xenophobia following his response at a press conference about the wealth of a few top clubs. During Sunday's match he appeared to spend a lot of time goading the Liverpool supporters (perhaps someone who was there could say if it was goading or good-natured bantz) and then seemed surprised when some of the idiots in the crowd threw coins at him. Klopp did not exactly cover himself in glory with his ridiculously OTT attack on the officials.
This is not new in football but it does seem to have notched up in recent years, and I am not sure whether the blame lies with the club's or the media. Oh for the days when managers did not feel they had to be a star of the team to feed the insatiable need for sensation of the media.
