Denmark's Holger Rune says he will be changing his diet in a bid to take himself to the next level after an inconsistent season. The 22-year-old, currently in action at the Stockholm Open, won the Barcelona title and reached the final of Indian Wells but has not quite been able to establish a top-10 ranking.

"I've talked a lot with my team after Shanghai. That was a big part of the frustrations I had on court," Rune told sports website SpilXsperten.
