Chelsea manager Mauricio Pochettino is facing mounting pressure to turn the tide at the club.
The former Tottenham and Paris Saint-Germain head coach has not made positive changes at the Stamford Bridge team so far.
Pochettino, who has to deal with a long injury list and a very young squad, has only a single win in six league games so far.
Speaking on talkSPORT, former Premier League forward Darren Bent believes Pochettino's job is in danger.
"Chelsea I almost feel are stuck in this kind of phase where, are they going to be a team that rebuilds or do they need instant success now?" he mused.
"Now, [Graham] Potter was supposed to be the one that rebuilt Chelsea but yet it was getting that bad they went, 'No, pull the plug.' I almost feel like with Pochettino, if this doesn't get better, they can say all they want about, 'Yeah we'll give him time, he's got to rebuild the squad.'
"If Chelsea, come Christmas time, are bottom half of the table and I'm talking like halfway between bottom and top ten, they might have to make a change."
