Boris Becker has appealed for help to locate several of his missing grand slam titles, which he had planned to sell to help pay off debts.
The six-time grand slam winner was declared bankrupt in June 2017 and was hoping to raise funds by cashing in on his memorabilia.
However, the German has been unable to locate several of his prizes and a widely released statement from Becker and his bankruptcy trustees called for help in finding the missing trophies.
The statement read: "A number of the trophies of Mr Becker's career are unaccounted for as Mr Becker is unable to recollect where they are located and various tennis institutions, including the All England Tennis Club, the German Tennis Federation, the US Tennis Association, Tennis Australia and the International Tennis Hall of Fame, do not appear to be holding the missing trophies.
"Mr Becker and his bankruptcy trustees are therefore issuing a joint appeal to the public for any information that may assist with locating Mr Becker's missing trophies."
Said to be among the missing items are the 50-year-old's three Wimbledon titles, two Australian Open championships and a gold medal from the 1992 Olympic Games.
Becker, who won his first grand slam title at the age of 17 at Wimbledon in 1985, now works as a television pundit and was previously the coach of former world number one Novak Djokovic.
