Under-fire Ipswich Town boss Roy Keane has launched a scathing attack on Dwight Yorke and has sensationally claimed that he has 'no respect' for his former Manchester United team-mate.

Keane reacted angrily to Yorke's assertion earlier in the week that the Irishman is an irascible, angry man who is too hot headed to become a top-class manager.

In his autobiography entitled, Born To Score, Yorke wrote: "I don't think the 24/7 care of a club manager is suited to his (Roy Keane’s) temperament. I don't think he can deal with everything that lands in the tray of a club man."

Yorke, who linked up with his old pal at Sunderland, also said that when Keane walked out on his job as manager at the Stadium of Light last December he sent him a text to wish him success in the future.

Keane responded: "Go f**k yourself".

However, the volatile Keane, not one for mincing his word, has predictably reacted furiously to the smiling assassin’s comments.

"I wouldn't agree I tried to rule by fear. I think it is important players are entitled to their opinions.

'Yorkie is trying to sell books - this might be his second or third book so he must be stuck for a few bob.

'I will take on board comments from people I respect but Yorkie is someone I don't have any respect for," he told BBC Sport as bluntly as ever.

The former Manchester United and Celtic midfielder was also critical of Yorke decision to return to the international scene by becoming assistant manager for Trinidad and Tobago and sternly questioned the 37-year-old's motives.

"He (Yorke) went back to Trinidad for reasons that have nothing to do with football," he said.
