A man’s nine-year-old daughter spotted a rookie mistake about Watford made on a popular ITV quiz show.

Si Parris aired his frustration today on Twitter after daily show Tenable named Watford FC among a list of London football clubs.

The father-of-two tweeted: “Erm, Watford isn’t in London. It’s in Hertfordshire. #tenable #watfordfc.”

He added: “This has happened loads of times before.

“It’s soo frustrating.” 

Tenable is hosted by Warwick Davis and involves teams of five trying to complete top ten lists based on general knowledge topics.
