More than 50,000 posts were researched and analysed on Twitter, conducted over a two-week period to July 7th, using club-specific hashtags to determine which fanbase used the most colourful language.
A spokesman at Paddy Power said: “Now the Premier League is back, it’s been a good opportunity to take a seat on our socially-distanced sofas and become the ultimate armchair fan. And by doing that, it seems it’s been a sweary time for football fans, too.
“Top of the profanity Pops is relegation-threatened Watford, and it’s hardly a surprise that Jose Mourinho is causing Spurs fans to dish out expletives – we can only imagine what their blood pressure scores must look like.”
