Jamie Vardy came to Leicester City training 'while he was still drunk'

Vardy moved from Fleetwood Town to Leicester, who were then in the Championship, for £1 million in 2012.

The striker struggled to adjust to the demands of the step up, and would turn up to training while still drunk.

Srivaddhanaprabha said in an interview with Thailand's a day magazine:

"Back then, I think he didn’t even have what it took to play in the Premier League. The day we bought him, he came to me and thanked me for changing his life.

"He had never had this much money so he was over the moon already. He went straight from the bottom to the Championship, which eventually led him to start drinking booze every single day. We had no idea what to do.

"I didn’t know about this until someone told me that he came to train while he was still drunk. So I went talk to him myself, I asked ‘do you wish to end your career like this? Do you want to stay here like this? We’ll let your contract run out, then release you. Don’t expect a better career path’.

"He said he didn’t know what to do with his life. He’d never earned such a large amount of money. So I asked him ‘what’s your dream? How do you think your life should be? Just think carefully about what would you do for the club. I invested in you, do you have to do something in return?’

"After that he simply quit drinking and started working hard in training. His physicality wasn’t as good as it is now. We know he had explosive acceleration, but we simply had no idea he could be this good."

The vice-chairman also revealed that he almost failed to sign Vardy, struggling to accept that a player from Fleetwood could be worth so much money.

"I was against signing Jamie Vardy in the first place. I asked Nigel Pearson and Steve Walsh about him, checked the scout reports, and I started to believe he would be a good signing, but I had to answer the supporters who were asking ‘how is a non-league player worth £1 million?’

"It turned out I was the dumbest club owner in the world to them.

"I asked Pearson and Walsh, if I have only £1m transfer budget for the next season, who would you buy? And they replied ‘Vardy’. Then I said ‘go’.

"There was outrage from the fans. Some even called me to say 'are you nuts? Why have you spent this much on a non-league player?'"

Vardy has been a key member of Leicester's title-winning squad. Suspended for the last two games, he has 22 goals for Leicester this season, and is expected to be included in England's Euro 2016 squad.
