Keane back on the attack after 'sing-song' row

Roy Keane has ramped up his criticism of his national side – and declared himself ready to take on anyone in the squad who disagrees with him.

In the wake of Ireland‘s tournament-ending 4-0 defeat to Spain on Thursday - their second Euro 2012 defeat in two games – Keane was highly critical of those involved in Gdansk and was annoyed by the way the players were serenaded from the stands despite their heavy loss.
