The Northern Irishman was widely condemned by the same group of supporters who once idolised him in Glasgow after he swapped Parkhead for the King Power Stadium in midweek.
Banners at both Tynecastle and Easter Road criticised Rodgers for his decision to leave the club he claims to have supported all his life. A video also surfaced where Celtic fans were singing: “I hope you die in your sleep Brendan Rodgers... with a bullet from the IRA.”
During Rodgers first match, which they lost 2-1, Leicester fans tried to get a chant of “we all hate Celtic” started. A video of the song was later posted on social media.
Hoops fans, however, were far from impressed with the lack of atmosphere in the 10-second clip and ridiculed it on Twitter.
@JBr1977 said: “I could barely hear that for the rustling of crisp wrappers and people sipping their lattes.”
@_andrewh1967 sarcastically added: “Best atmosphere av seen in long time.”
While @VinnyCSC said: “As a Celtic fan I can say that really hurts! 4 guys at a wee stadium somewhere don’t like us?”
