Chris Sutton has expressed concerns over the standard of Brendan Rodgers' current Celtic squad.
Sutton is bewildered by the displays of Kieran Tierney and Reo Hatate, who have failed to spark in a season where the champions have rarely impressed.
"I don't know what has happened to Reo Hatate this season, but he's miles off it."
A crucial period is coming up for the Parkhead club, with four Premiership games, a Premier Sports League Cup semi-final against Ibrox opposition, and two Europa League outings.
Sutton reckons Rodgers will have to turn to his old guard to address the team's performance.
