MARIO BALOTELLI has reignited his feud with Brendan Rodgers - branding the former Liverpool boss the worst coach of his career.
And the Italy international dubbed Celtic manager Rodgers "a disaster" as a human being.
Liverpool signed former Manchester City maverick Balotelli from AC Milan for £16million in 2014.
However he scored just one goal in 16 Premier League games for Rodgers' side, and four in 28 all told.
The Reds loaned the striker back to Milan, and Rodgers' replacement Jurgen Klopp let him leave for Nice on a free transfer in 2016.

Balotelli, in a second spell with Turkish club Adana Demirspor, has now let rip at the Northern Irishman.
The 33-year-old told TVPlay: "Brendan Rodgers is the worst coach I have ever had.
"He was number one as far as training sessions were concerned, what with keeping possession of the ball and the small-sided games.
"But as a person he was a disaster."
Rodgers, 50, has previously criticised Balotelli's lack of input at Anfield after being signed to replace Luis Suarez.

The former Inter Milan star has had a chequered career, also playing for Marseille, Brescia, Monza and Swiss club Sion since leaving Merseyside.
Rodgers currently has Celtic first in the Scottish Premiership after taking over from Spurs boss Ange Postecoglou.
But the Hoops crashed out of Europe on Tuesday following their 2-0 loss at the hands of Serie A side Lazio.
