Former West Ham defender Tomas Repka has been convicted of fraud and sentenced to 15 months in jail.
The Prague district court ruled that the 45-year-old sold a luxury car to a woman even though he did not own it.
The former Czech Republic international and Fiorentina player had been renting the car at the time.
In a deal Repka signed, he promised to return the money if the ownership was not transferred to the woman, but he did not do that.
Thursday’s ruling is not final. Both Repka’s lawyer and the state prosecutor immediately appealed.
It is not the first time Repka has been in trouble. Last year, he received a six-month jail term for offering sexual services in the name of his former wife.
That was later changed to community service. He also twice received suspended sentences for drunk driving.
