The 46-year-old has told The Sun: “It’s true, I do have an IQ of 150! I was tested at Chelsea in the aftermath of John Terry getting kicked in the head in the Carabao Cup final. Our doctor, who was Brian English at the time, made us do IQ tests to get us all a base-level IQ so we could be registered again if you had a concussion or a head injury.
“I just breezed it. Other people seem more interested in it than me. But I am quite proud of it. My score of 150 just beat my wife, Christine, which was the best thing about it. She was just below me. I don’t know the exact numbers but we were around the same. But I think she’s smarter than me — at least it feels that way in the house!
“It was a strange test. I’d never done one before. For whatever reason, I came out on top of it. That was my one and only IQ test. I retired after taking one, just in case it was a false test!”
