Bradford City have reportedly sent a letter to American singer Diana Ross to help her improve her penalty-taking skills.

The 68-year-old famously missed a penalty from five yards out during the opening ceremony of the World Cup finals in Chicago in 1994 and the League Two side, who recently secured their ninth consecutive penalty shootout victory in a League Cup quarter-final clash against Arsenal, believe that they can help the songstress.

"We would like to improve Diana's record by sharing some of the squad's techniques and hopefully help Diana learn how to take penalty kicks with the proper skill set," the Daily Mail quotes the tongue-in-cheek letter as saying.

The letter also claimed that Bradford's penalty shootout success is an unofficial world record.
