ADELAIDE believes it will be cleared of any wrongdoing over the recruitment of small forward Eddie Betts and expects an AFL investigation over the matter to be concluded by the weekend. 

The Crows confirmed to AFL.com.au that Betts and head of football David Noble had both been interviewed by the League after CEO Andrew Fagan initiated contact to prove the club's innocence.

Betts' manager Ned Guy has also met with the AFL's integrity department as it looks into contract negotiations between Adelaide and the former Carlton forward.

The AFL on Wednesday confirmed it has interviewed eight people as it examines the Crows' recruitment of Betts, and "has not received any information indicating that a breach of the rules has occurred."

Its inquiry, which remains ongoing, comes after sacked Carlton coach Mick Malthouse claimed Betts had an agreement with the Crows 18 months before he left the Blues.

Under AFL rules, players cannot sign with a rival club while under contract, with Malthouse's allegation coming as a side story on the same day he was axed after two-and-a-half seasons with the club.

Carlton CEO says Malthouse's claims incorrect

Guy took to Twitter to say Malthouse's claims were "100% incorrect" and met with the League's integrity officers on Wednesday to explain his client's situation and contract dealings through that period.

AFL.com.au has contacted the League for comment.

Malthouse aired the suggestion in an explosive interview on Melbourne radio station SEN on Tuesday morning, which was the final straw for the Blues' board, which terminated his coaching contract later that day.

The veteran coach said he would have preferred Betts stay with the Blues instead of crossing to Adelaide as a restricted free agent at the end of 2013, but was told by Carlton CEO he was "stitched up" before he officially moved to Adelaide.

"I'd still love to have a number of players here. Betts is the most classical one, because he's a goalkicker," Malthouse said.

"But Steven Trigg assured us when he arrived here 'Don't take it too personally, we – being Adelaide – had him stitched up 18 months out'.

"So it's very, very difficult when you come to a football club and a bloke like that plays very cautious football because his heart and soul, certainly his mind, was everywhere else.

"He tried to do the right thing, but when you've got that load of 'Will I go, won't I go, but I've already signed' … so we lose that sort of player."

The Crows also angrily denied any suggestion of wrongdoing, releasing a statement on Tuesday night. 

"The Adelaide Football Club categorically denies any inappropriate dealings regarding the signing of forward Eddie Betts.

"We are extremely disappointed by comments made to the contrary today.

"The Carlton Football Club and Betts' manager have also publicly refuted any suggestion of wrongdoing by our club."

The Crows have also supplied documentation to the AFL relating to Betts' signing. 

Betts is second in this year's Coleman Medal race with 29 goals, two behind West Coast's Josh Kennedy.
