'That's not allowed is it?': Fabio Fognini's insane winner stuns commentators at Wimbledon

Italian star Fabio Fognini has produced one of the shots of the tournament at Wimbledon in his third-round clash against No.5 seed Andrey Rublev.

With the match tied at one set apiece and Fognini looking to force Rublev to serve out the third set, the 26th seeded Italian pulled out an incredible backhand winner.

Rublev looked to have won the point when his stinging two-hand backhand forced Fognini deep into his own corner before he unleashed an incredible one-handed passing shot.

The insane winner stunned Nine's commentary duo of Todd Woodbridge and Sam Groth, with Woodbridge comparing it to a Roger Federer shot.

"Stop it! That's not allowed is it?" Woodbridge said on Nine's Wimbledon coverage.

"I say that because it's usually with the two-hander and somehow he flicks single-hander with something Federer would be proud of."

"I don't think the physics of this quite work do they?" Groth added.

"I'm not sure how that's gotten over the highest part of the net and dipped down into the court."

Fognini's third-set heroics came after a dominant second set where he showcased some incredible hitting that allowed him to get back into the match.

However, despite Fognini's heroics he was unable to take out the third set, with Rublev serving it out the ensuing game to take a two set to one lead before sealing the match with a 6-3 5-7 6-4 6-2 win.
