DANIIL MEDVEDEV lost his cool - and his COACH - and left his wife in tears in an explosive Halle Open final defeat to Hubert Hurkacz.
The Russian tore into his coach at the start of the second set after he was broken in the first game.
Medvedev, 25, lost the first set 6-1 and allowed his anger to boil over, unfortunately for his coach Gilles Cervara.
The Russian began screaming at Cervara who decided to get up and leave the arena in Germany rather than put up with any more abuse.
Cervara was seated next to Medvedev's wife Daria, who held her head in her hands after her husband's outburst and appeared to wipe away a tear.
She looked like she wanted the ground to swallow her up as the camera zoomed in on her face - but Medvedev did at least apologise to her after his 6-1 6-4 defeat.

He said: "Daria, thanks a lot for this week. Not easy to be with me on the court sometimes but hopefully next time will be easier and much better.
"Also thank you guys [the crowd] very much, sorry for not making this match longer and more interesting!"
Daria watches all of her husband's matches and acts as his personal assistant - arranging trips and his financial accounts.
Daria also played tennis at junior level but injury cut her career short, with the Russian later turning to modeling.
