Sutton: Martin O'Neill is responsible for Celtic's problems

Celtic lost 2-0 to Falkirk. Scott Tanser's well-taken second goal came after an early strike from Ethan Ross, and once again the Hoops' defensive weaknesses were exposed. Falkirk's win was their first against Celtic since 2007. Celtic failed to extend their four-point lead in the Scottish Premiership and missed the chance to go seven points clear at the top.

Celtic have won three of their last 10 matches in all competitions. Sky Sports pundit and former Celtic striker Chris Sutton described the team as being in "decline". Sutton said he did not know which 11 Martin O'Neill would field, and compared the situation to a lottery.

Celtic have lost all three of their Champions League matches so far. Their next opponents are Beşiktaş. Criticising their European performances, Sutton said Celtic had fallen behind teams from Azerbaijan and Armenia.

The coaching work of Shaun Maloney and Mark Fotheringham is also being debated. For Sutton, however, the real question is this: does the responsibility lie with the coaches, or with O'Neill? Sutton answered immediately. O'Neill hires the coaches, he said, and O'Neill determines the training and the style of play.
