Boris Becker:  Former German tennis icon Boris Becker is returning to the sport as the 55-year-old announced that he will coach Danish shooting star and world number six Holger Rune.

"We over some time kept in contact. I like his emotional way on the court as I pretty much was the same," Becker said.

The collaboration is said to at least last until the end of the year and includes the ATP tournaments in Basle, Paris and Turin, Xinhua reports.
