Neil Lennon has warned furious Celtic supporters should be "careful what they wish for".
The former Celtic boss defended the Parkhead hierarchy as he responded to the toxic atmosphere that brewed during the loss to Hearts.
Supporters were left angry as goals from Lawrence Shankland and Stephen Kingsley condemned Celtic to defeat.
Chants of 'sack the board' and 'Lawwell get to f***' were then heard inside the stadium as tempers flared.
However, Lennon suggested there is no need for any overreaction despite the team performing below expectations on a handful of occasions so far this season.
On PLZ Soccer, Lennon explained: "I don't think there's any need to panic. You look at the record and it's the first time in ten years they've lost back-to-back games and the first time they've lost at home in 52. It's a really high bar and records are there to be broken.

"But you have to say the level of performance isn't what we expect from Celtic at the minute so they're going to have to dig deep and galvanise everyone around. The fans need to see that the team is going through a bit of adversity and this is when the team and the manager need their support, rather than the other way around.
"I know there was some dissent towards the board, which I don't understand because they've just won a Treble last year. Since Dermot's come in it's been total domination for 20 odd years; six Trebles, Europa Leagues, three last 16s, I could go on.
"So sometimes you've got to be careful what you wish for. But at the minute, it's not good. There's a lack of consistency and I think Brendan's waiting for the January transfer window. Currently, he has to roll up his sleeves and get more out of this team."
