Stefanos Tsitsipas opens up on his relationship with Mark Philippoussis

Greek tennis star Stefanos Tsitsipas reveals he feels Mark Philippoussis has "good values as a person" and revealed the 2003 Wimbledon finalist used to give him some advice and tips in the past.

Philippoussis, a retired Australian tennis player of Greek and Italian descent, was once considered as one of the most talented players on the Tour but he never won a Grand Slam or reached the top spot.

However, Philippoussis still enjoyed a very notable career as he was a two-time Grand Slam finalist and was once eighth-ranked player in the world. "We've been collaborating in the past a little bit. He's a good friend of ours.

We also speak the same language. I think there's good connection with him, which matters a lot. Not only on the tennis court, but I think he has good values as a person," Tsitsipas said of Philippoussis, per Ravi Ubha on Twitter.

Tsitsipas was beaten by Kyrgios in Halle two weeks ago and the Greek will certainly be extremely motivated to get a revenge.
