Sunderland boss Keane has no problems with Clarke
Clarke gave a damning verdict of Keane's approach in an interview in Ireland and Keane confirmed he will deal with the matter internally.
"I have not seen anything but I have no problem [with it]," added Keane.
"All players are entitled to their opinion like everybody else, but obviously going through the media is a different matter
"I think Clive has played one or two games for me but that will be dealt with in-house, trust me."
