The Porsche Macan owned by Liverpool star Philippe Coutinho reportedly suffered damage after a man hurled a rock at the £60,000 luxury car.
The Brazilian was not in the vehicle at the time, having parked up outside Anfield to attend Liverpool's end-of-season awards with his wife Aine.
According to the Daily Mail, a man arrived in the gated car park and threw the rock that smashed a window on the drivers' side before running away.
It is believed that a police van later arrived at Anfield and a member of staff accessed the car to look over the damage.
Coutinho's future has been a talking point this season, with reports claiming that Barcelona are interested in signing the 24-year-old, despite the fact that he penned a new long-term deal in January.
