Manchester City showed no mercy when they hammered Chelsea 6-0 at the Etihad Stadium in Sunday's Premier League clash.
Three goals from Sergio Aguero and a Raheem Sterling's brace with Ilkay Gundogan stunner ensured the Citizens return to the summit of the league table.
The defeat was Maurizio Sarri's heaviest defeat since he took over from Antonio Conte in August 2018.
SunSport however reports that City fans chanted "You need Mourinho " during the disappointing clash at Etihad Stadium.
The Blues have also slipped to sixth on the table, though with 50 points from 26 matches - 15 behind Pep Guardiola's side.
Manchester Evening Standard writer Samuel Luckhurst agreed with City fans and joined in the criticism of Sarriball.
He wrote on Twitter: "Much to like about Sarri and he was parachuted in, but he's not been helped by the hipster hype and the cringing 'Sarri ball'. "His Chelsea are doing worse at City than Mourinho's United and Emery's Arsenal. "
The Portuguese born tactician led Chelsea to three Premier League triumphs in two stints at the club: between 2004 and 2007 as well as 2013 and 2015.
But he was unable to save his job at Manchester United in December in his third season after a terrible run of form saw the Red Devils drifting away from the Premier League top four.
Meanwhile, his successor, Ole Gunnar Solskjaer, has led United to 10 wins out of his premiere 11 games in charge of the club.
Blues fans flooded social media with the #SarriOut hashtag as the goals at the Etihad kept on pouring in.
