Rab Douglas has reignited his war of words with John Brown after claiming the tape recording he has of their explosive meeting will 'embarrass' his former Dundee boss.

The pair had a public falling out when Steve Simonsen replaced Douglas as No.1 on Tayside in 2013, which the keeper claimed he was informed of five minutes before the signing was made public.

The former Celtic star spoke out at the time, but that was just the start of it as Brown responded by exclusively telling Record Sport Douglas was a 'disrespectful liar'.

In an explosive interview, the Rangers legend refused to hold back and even warned off potential suitors over signing Douglas.

Now the keeper has hit back more than four years later and he says there are two sides to every story – and has vowed to reveal in his autobiography exactly what Brown said to him.

Douglas told BBC Sport: "There's only winner and that's the manager and he won. There's no doubt about it but it's there for a book. There's a bit more to it and he had his say, so I'll have mine soon."

The goalkeeper, 45, admitted he may have crossed the line with some of language he used during the fiery confrontation.

He added: "Probably after he told me to get my stuff and get, yes, and only after that.

"John Brown's had his say in the back of the papers and I'll have my say some day."

When asked how the transcriptions will make Brown look, Douglas admits the fallout will be "slightly embarrassing for him".

Douglas admits the accusation over his character hurt, but he points to his long career in the game as a reason why 'Bomber' was way off the mark.

He said: "I think when you look back, 19 when I started at Meadowbank, that's 20 odd years and to be still involved isn't bad for a disrespectful liar – 600-odd games."

Former Dundee boss Brown said during the confrontation that he taken aback by what Douglas had to say to him.

He said in June 2013 : “When he got into the office, the player was raging. He called me a ‘sh*****’ and a c***’.

“I’ve been in the game a long, long time but I’ve never heard a player talk to a manager in that manner."
