Following a rematch between the two bad boys of tennis, a duel will take place between two tennis beauties - this year's ATP tournament in Umag guarantees excitements from the get-go until the grand finale on Sunday, July 24. The oldest ATP tournament will open on Saturday, July 16, with a rematch between Goran Ivanišević and Andre Agassi. However, that will not be the only exhibition match during the 27th Konzum Croatia Open Umag.

On Wednesday, July 20, at the ATP Stadium in Umag, the 2015 US Open champion, Italy's Flavia Pennetta, and the promising Croatian, four-time WTA finalist Donna Vekić, will demonstrate the magic of the top-quality ladies' tennis. In her comeback, the tennis legend Flavia will be joined by her fiancé Fabio Fognini, while Donna will team up with our own legend, Goran Ivanišević.

"Even though this has always been a men's tournament, we female tennis players also like to come to Umag as it is a city with a fantastic tennis atmosphere. I look forward to playing the match at the ATP Stadium in Umag and seeing Flavia again. It will be a unique experience in my career so far, particularly as I will be on the court with both Goran and Flavio, and it's never boring around them," Donna Vekić, currently ranked 95th in the world, said.

As for Flavia Pennetta, Italy's 34-year-old tennis icon, her performance in Umag will mark her return to tennis, following last year's retirement, shortly after winning US Open. Her life and tennis partner Fabio Fognini is one of Umag's most loyal guests, Italian fans' favorite and one of the most charismatic players on the ATP Tour.

"After I take my revenge against Agassi on Saturday for beating me 24 years ago, it will be my pleasure to play alongside Donna on Wednesday. Fabio has always been one of my favorite players and we are similar in character. Also, Flavia achieved her biggest success quite late in her career, just as I had done in Wimbledon. We are rather similar and there's loads of reasons for us to have great tennis fun, and the tournament in Umag is an ideal place and time," Goran Ivanišević explained.
