Newcastle United legend Alan Shearer can't believe the demise of Chelsea.

He wrote in The Sun: "Can there be a more bizarre football club than Chelsea?

"If anyone ever needs reminding that this game is mad just look their way.

"Only Chelsea, it seems, could have the potential to implode so dramatically from what was undoubtedly the greatest day in their history.

"Who could have predicted that from that marvellous night in May in Munich they could be here?

"A club fighting with itself.

"A club constantly in the news for the wrong reasons.

"From the John Terry racism case to the unseemly treatment of Premier League referee Mark Clattenburg.

"The man who masterminded their finest achievement gone and his replacement booed before he has heard the first whistle. Jeers now ring round a stadium which has previously enjoyed so many highs."
