MARK MCGHEE has revealed his bizarre methods of preparation ahead of Dundee's do or die showdown against St Johnstone on Saturday.

The Dens Park outfit need to win and secure three points to have any chance of remaining in the Scottish Premiership.

Saints are currently three points ahead of their Tayside rivals and McGhee knows his team are running out of time.

And asked about his preparations for the match, the former Motherwell and Aberdeen boss revealed a unique plan of action.

He said: “It requires no stone being left unturned because when the boys run out there on Saturday then we need to be able to say we have done everything we can to help them get a result.

“I was trying to make a point with this with Charlie Adam on Monday and he ended up taking the mickey out of me.

“There are two things I am doing this week to focus on getting the win.

“The first thing I have done is to go on a diet so I am hungry all the time.

“I then ask myself why am I hungry and I am hungry because there is a big game on Saturday.

“The second thing I am doing – and I have told Charlie I am doing this – that I won’t be using any heating (at home).

“So I will be cold. I then ask myself why am I cold? I can say because of the game on Saturday.

“It is not the two things of being cold and hungry but it is the principle of them because I am asking my own players to make this game as important in their own minds.

“I want them to focus on the game and this is what I am doing to make sure they are focused.

“For the rest of this week I will be on a strict Lesley Strachan diet and I won’t be using the heating, trust me.

“It is a psychological thing for me because when I get here on Saturday then not only will I feel I have done everything but I will also be able to feel I have given everything.

“So I might feel more deserving of a good result.

“That is the way the players need to think.

“We need the players to change because if they keep doing the same things as they have done then it is the Einstein adage that if you keep doing the same things and expect a different outcome then it is madness.

“To change you have to change something and this is what I have adopted as part of the process.

“Charlie says I am off my head.”
