Chelsea fans probably didn’t think their season could get any worse after losing 4-0 at Bournemouth at the end of January.But it got a whole lot worse on Sunday.Maurizio Sarri took his side to the Etihad and they were well and truly embarrassed.Manchester City were 4-0 up inside 25 minutes and went on to win 6-0.If that humiliation on the pitch wasn’t enough, someone inside the stadium decided to humiliate them even more.The person in charge of the PA system chose to play ‘One Step Beyond’ by Madness.Of course, the anthem has been adopted by Chelsea and is often played after they win at Stamford Bridge.And City fans clearly enjoyed rubbing it in the faces of the few remaining Chelsea fans inside the stadium.

However, the song was quickly turned off the PA system and now according to the Evening Standard, City have apologised to Chelsea.

The report says: “Manchester City apologised to Chelsea for playing the Londoners’ victory anthem ‘One Step Beyond’ after Sunday’s 6-0 rout. 

“Senior City officials ordered the Madness song be cut short and were quick to say sorry to the visitors for what could be interpreted as an act of gloating.”

City weren’t the only ones who had to apologise for their actions after the final whistle.

Chelsea boss Sarri also had to issue an apology for his actions at full-time.

He seemingly ignored Pep Guardiola’s handshake and later claimed that he hadn’t seen his opposite number.

"I didn’t see him at the time but I will go to say hello to him later, as usual," Sarri explained at his post-match press conference.

"I wanted to go to the dressing room and in the moment I didn’t see him. I have no problem with him."

It doesn’t get any easier for Chelsea, either.

They travel to Sweden to face Malmo on Thursday in the Europa League, before a FA Cup clash against Manchester United.

A return tie against Malmo follows before the Carabao Cup final against Man City.

London derbies against Spurs and Fulham come next before they take on Wolves and Everton.

Ouch.
