SAM Allardyce is suing Steve Kean and considering the prospect of taking legal action against Blackburn after the Rovers manager's astonishing attack on YouTube, Telegraph Sport can reveal.
Allardyce, the current West Ham United manager, has instructed his lawyers to initiate proceedings against Kean, his successor at Ewood Park, following allegations that have created an internet storm.
Allardyce is furious about the inflammatory remarks made by Kean doubting his integrity, his operating methods and ability as a manager, that were filmed by Blackburn fans during the club's pre-season tour of the Far East last summer.
He is also ready to sue his former club in a move that will only increase the pressure on both Kean and the Indian owners, Venky's.
Kean was set to meet his bosses for talks in Pune today, following Blackburn's relegation from the Premier League.
Allardyce was controversially dismissed at Ewood Park in Dec 2010 and is determined to take the matter to court.
Talks were held with his solicitors on Tuesday lunchtime after several viewings of the footage on YouTube.
Kean could be in further hot water with the game's authorities after his four-minute rant in a Hong Kong bar.
He has maintained that his position is safe with Venky's but this latest episode will only increase the pressure on his shoulders.
