Boris Becker has announced the end of his collaboration with Holger Rune. The former German champion has been working with Rune for four months.

Rune has had an up-and-down start to the season, losing in the group stages of the ATP Finals in Turin and in the second round of the Australian Open. The Dane has also lost in the semi-final of the Open Sud de France. Becker's departure follows the departure of Roger Federer's coach Severin Lüthi.
