Is Roy Keane playing with fire at Sunderland?

Another great article from former Republic of Ireland forward Tony Cascarino, where Tony questions the recent signings that Keane has made including Pascal Chimbonda, El Hadji Diouf, and Djibril Cisse. I disagree with Tony on his views though as I think Roy is doing the best he can within his resources to bring in players that can help make Sunderland a respectable team within the Premier League and keep them out of a relegation battle.
