Celtic hero Chris Sutton has denied any fears that the Hoops are experiencing a "crisis".
The Scottish champions lost 2-0 at home to Hearts yesterday as they continued their run of being unable to win three games in a row this season.
Despite this and the Parkhead side's poor European campaign, Sutton has dismissed fears but did admit Brendan Rodgers' men need to improve.
Speaking on BBC Radio 5 Live, he said: "Crisis club Celtic? Still top of the league, an insipid performance today by all accounts and there are Celtic fans out there who will blame the board.
"They can blame the fact that there’s a section of the Celtic support which still aren’t allowed inside Celtic Park.
"But surely Brendan Rodgers has to take some responsibility. He’s gone back, last season it was Angeball, but the level of performance has really dropped this season and Brendan has to carry the can for that.”
Meanwhile, Rodgers issued an apology to furious Celtic supporters after the2-0 loss to Hearts.
The Parkhead boss admitted his side were far below par in the Scottish Premiership defeat but revealed he wasn't overly surprised as standards slipped.
Supporters made their feelings clear with the team booed off the park after the defeat and chants of 'sack the board' and 'Lawwell get to f***' heard inside the stadium.
Rodgers said on BBC Sportsound: "Firstly, it's an apology to the support base. I don't think I've ever had to do that in all my time here, the first time or this time.
"Certainly, the performance today was nowhere near the level of what is expected as a Celtic player and a Celtic team.
"We lacked any desire in our defending, we lacked that drive when we had the ball and that intensity.
"And like I said, it felt like we could have played all night and not scored."
