In the long history of Roy Keane rants, this was one of the most jaw dropping.

During a media event this week Keane savagely attacked recently retired Irish striker Jonathan Walters for discussing losing his brother, his daughter being diagnosed with scoliosis and his wife having a miscarriage on the Late Late Show in May.

“On TV, crying about his family situation,” Keane sneered as he discussed Walters during the Off The Ball Roadshow in the Bord Gais Theatre on Wednesday night.

“You know, how about lying low for a while, taking it easy?

“Have a look at his medals? Wouldn’t take long.”

What made Keane’s comments even more unpalatable was the fact that all money raised from ticket sales at the event are to be donated to Aware, a charity which aims to assist people affected by depression, bipolar disorder and related mood conditions.

So was it acceptable for Roy Keane to mock Walters for expressing his emotions regarding some very traumatic family issues?

The pair do have history and the start of the feud can be traced back to August 2010 when Keane was Walters’ manager at Ipswich Town.

According to Walters, Ipswich said he would not be leaving the club unless their valuation was met.

This led to some serious confrontations, which almost saw them come to blows a few times, before Walters sealed a deal to Stoke City for nearly £3 million.

They again fell out during the final days of Martin O’Neill and Roy Keane’s regime with the Ireland national side.

Since retiring at the end of last season Jonathon Walters has discussed his confrontations with Keane on several media appearances, something which has obviously seriously annoyed Roy Keane.

Walters has said nothing regarding Keane’s comments yet but did take to Twitter yesterday, with a picture of him wearing a boxing glove with the caption: “Insert face here.”

This led to many of his followers putting up pictures of Roy Keane’s face in reply to the Tweet.
