And this is a new low, for not only Maurizio Sarri but also for the Blues.
The 4-0 loss is the heaviest Premier League defeat that the Blues have suffered in more than 20 years and now many are wondering whether the Italian manager will be able to last the full season at the Bridge.
It is being reported that the manager was furious after the loss to the Cherries and in a bid to find out what went wrong the manager locked his players inside the dressing room for more than an hour.
While many fans will be happy that their manager is taking such bold steps but Celtic manager Brendan Rodgers feels that the Italian is doing it all wrong.
Speaking to Alan Brazil and Dean Saunders on Thursday’s Sports Breakfast, the former Chelsea coach said: “When I started coaching over 20 years ago it was very different.
“I always think with players you can still tell them, but the world and society has changed and that means football has changed too and players are now more protected.
“Years ago, when you guys were playing, you’d have worked with managers who sometimes to be clear had to be very harsh, but you took that on. You took that on and you probably said to yourself, ‘I’m going to show them that I’m better than that’.
“Whereas now, and this is not all players because I’ve worked with some brilliant lads who you can be harsh with, but a lot of players will take it differently now.
“The culture is also now much more diverse and in their culture, they might not have that.
“It’s becoming much more difficult, but you have to adapt to a manager and that’s very important.”
The 4-0 loss means that Chelsea have now slipped down to the fifth spot on the Premier League table and with each passing game the dream of getting back into the Champions League seems to be fading away.
