Former Celtic defender Erik Sviatchenko says the club was chaotic under Ronny Deila.
The Danish international was brought in by the Norwegian in 2016. Sviatchenko was fantastic and continued under Brendan Rodgers to become an invincible.
However, the 27-year-old revealed the club changed when the Irishman took the reins.
Sviatchenko comments on Celtic managers
The current Midtjylland star has waded in on the Deila and Rodgers debate.

He has given a first hand account on the differences between the two bosses at the club.
He told Four Tims and a Podcast: “The six months under Ronny Deila was a bit chaotic – he was a good manager and a good man but the club wasn’t where it was supposed to be.
“When Brendan Rodgers came in it really changed the atmosphere around the club and it got the status of being this majestic club in some way that went back to the Champions League.
“It was two different periods under Deila and Rodgers but I enjoyed both of them. We kicked on after summer 16 when Rodgers came in with his new staff.”

Sviatchenko reveals that even the smallest of details made the difference between the two bosses.
Rodgers wanted us in matching suits says Sviatchenko
The former Celtic man says Rodgers went through every detail with a fine tooth comb.
He used the semi-final defeat on penalties as an example of where the club needed to change.
The Dane believes this is the turning point between the two managers.
Sviatchenko said: “He said he watched the semi-final against Rangers and we were dressed differently as Rangers were all suited and booted and it was strange he reacted in the way he did.

“After that we had tailored suits for the finals, but it’s the small details that gets you to the winning stage.”
Sviatchenko is playing at his best with Midtjylland after falling out of favour with the Irishman.
He is currently player of the year, but is open to another move abroad in future.
