Chris Sutton: Celtic's Carter-Vickers Must Focus on Performance

Former Celtic striker Chris Sutton has questioned defender Cameron Carter-Vickers after his recent displays. It's been a tricky period for the Scottish club, with inconsistent performances ramping the pressure up on manager Martin O'Neill. Their displays in Europe have been particularly disappointing , while perhaps being fortunate to have picked up as many points as they have in the league. There have been many calls for O'Neill to be sacked due to some of the decisions he's made, which is always interesting considering they're still top of the Scottish Premiership.
