Manchester United midfielder Casemiro wears the wrong name on the back of his shirt, and has done so for his entire career.
The Brazilian midfielder, who joined United from Real Madrid over the summer, has Casemiro - with an E - on the back of his shirt. However, his name is Carlos Henrique Casimiro - with an I.
He has opened up about the strange situation, explaining the difference in spelling owes a bit to superstition dating back to his time at Sao Paulo. When the 30-year-old takes to the field with the different spelling, it's down to a mistake which has not been corrected in more than a decade, but he had a part to play in it not being corrected.
"So the thing is, my name is Carlos Henrique Casimiro, with an 'I' there," Casemiro told Football Focus. "I remember that I played a game for Sao Paulo and they got my name wrong. They wrote it with an 'E'.
"I played really well in that game and as I'm a superstitious person, I said to them 'just leave it like that, as things are going well'. So the name stuck, but my name is Carlos Henrique Casimiro.
"It was a mistake made in one game, the name stuck and I said: 'No need to change it, leave it as it is'."

Since establishing himself in United's first team, Casemiro - or should that be Casimiro - has shown his value to Erik ten Hag's team. He missed a crucial trip to Arsenal through suspension, though, and now faces more time on the sidelines after being shown a straight red card in a league victory over Crystal Palace.
The former Real Madrid man was sent off by referee Andre Marriner following a VAR check after putting his arms round the neck of Palace midfielder Will Hughes. He will miss two league games against Leeds and one against Leicester before returning to domestic action in the Carabao Cup final.
"Casemiro crossed the line; you saw that," Man Utd's manager accepted after the match at Old Trafford. However, I'm unhappy with the inconsistent refereeing; not only this game but also [away to] Palace.
"They elbowed Martinez and last week with Eriksen. A lot of other players crossed the line, including some Crystal Palace players. VAR didn't intervene with them."
Goals from Bruno Fernandes and Marcus Rashford helped United open up a two-goal lead against Palace after drawing with the Eagles in the reverse fixture. Jeff Schlupp pulled a goal back for the visitors after Casemiro was given his marching orders, but the visitors were unable to find a crucial second goal with their man advantage.
