Premiership stars seeking treatment from therapist Mariana Kovacevic could be left in limbo after she did a runner from Serbian authorities.

The Sun says Kovacevic became famous for using horse placenta to treat crocked Arsenal star Robin van Persie.

Chelsea's Frank Lampard and Glen Johnson of Liverpool also flew out last week in search of an 'alternative' cure to injury woes.

But Kovacevic is wanted by the Belgrade authorities as she does not appear to have the correct licenses.

She is also being investigated by Serb tax officers as her company is not officially registered.

Health inspectors, along with the police, attempted to gain access to her offices last week but she refused to answer.
