O'Neill agrees with McGregor about Celtic issues

Celtic still hold a four-point lead at the top of the Scottish Premiership, and will extend that to seven if they beat Falkirk on Sunday, with Rangers in League Cup action.

The defending champions have only lost once, at home to Rangers, in the league but have three Europa League defeats from three amid fan discontent and a boycott of some games by the Green Brigade fans group.

McGregor is not the first senior player to speak about Celtic's lack of control in games, with defender Cameron Carter-Vickers saying after their Glasgow derby loss that the team were "too random" in their play.
