The Russian-born Lithuanian businessman has seen the Edinburgh club fall into administration following eight years at Tynecastle and MacDonald has survived to tell the tale of his nightmarish control.

"The odd time he'd come in for meetings and do a little speech through his interpreter. Some of the meetings were mental to say the least, with threats and what not, especially in the early days.

He added: "Did I see this coming? Probably, yeah. The last three years especially there have been numerous times when we've gone without getting paid for a couple of months at a time.
"You kind of realise administration is probably inevitable but at the same time you think it's going to be all right.
"For some reason we managed to be okay in the past but this time it has come to a head. But at least everyone knows what is happening now."
