Denny Solomona was 'fired' by Castleford before joining Sale, says Steve Diamond
Sale director of rugby Steve Diamond claims Castleford "fired" Denny Solomona before he joined the Sharks.
The 23-year-old winger switched codes from rugby league to union in a move which prompted the Tigers, with the support of the Rugby Football League, to start legal action.
New Zealand-born Solomona shot to prominence in 2016 with a Super League record 42 tries but failed to report for pre-season training after Castleford rejected three offers for the player towards the end of last term.
Solomona had two years remaining on his Castleford contract, but Diamond - who had previously claimed the player "resigned" from rugby league - believes his club have done nothing wrong.
"It's in the hands of the legal people, but I don't see any problems at this moment," Diamond told BBC North West Tonight.
"I'm confident that we made a substantial offer and it was knocked back.
"For various reasons Denny became available through being fired from Castleford and once he'd been fired we got in touch and signed a contract."
Solomona made his Sharks debut in Sunday's 24-10 European Champions Cup defeat to Saracens, having officially joined the club on a three-year deal five days earlier.
Castleford, who are seeking damages against Sale and Solomona's agent Andy Clarke for allegedly inducing a breach of contract, have appointed leading London barrister Nick Randall QC - whose other clients include England captain Wayne Rooney - and Leeds-based sports lawyer Richard Cramer to fight their case, which is expected to be heard at the High Court in Leeds.
RFL chief executive Nigel Wood has expressed his concern to both the Rugby Football Union and Premier Rugby, and welcomed the Tigers' tough stance.
Wood said last week: "As we have previously stated, the RFL believes that it is a fundamental point of principle for all sports that both players and clubs adhere to the terms of signed contracts between them.
"It is therefore not surprising that when a club believes the terms of a contract have been broken, they may issue legal proceedings to protect their position."
The RFL is also investigating Clarke, who is an officially accredited agent.
Castleford were not available for comment when contacted by Press Association Sport on Tuesday evening.
