Roger Federer has dismissed rumors of reunion with former coach Stefan Edberg. The duo had worked together for two years before parting ways in December last year.

The reports of a potential reunion started to circulate after Edberg was spotted in Federer’s box during the 17-time Grand Slam champion’s fourth round match against American Steve Johnson at the Wimbledon Championships on Monday.

However, Federer, who works with Severin Luthi and Ivan Ljubicic, dismissed rumors of a second stint with Edberg. “Severin and Ivan remain my coaches,” the 34-year-old was quoted as saying by puntodebreak.com.

Meanwhile, Federer will look to continue his quest for a record eighth title at the All England Club when he takes on Marin Cilic of Croatia in the quarter-finals on Wednesday.
