The Blues are slumped in 10th place – 14 adrift of fourth place Tottenham – having won just one of their last 11 matches in all competitions.
The club have managed to score just four times in that woeful run and have failed to record a win away from home since mid-October. Defeat to Spurs on Saturday piled more pressure on Potter, who was only appointed at Stamford Bridge in September.
Should Chelsea pull the trigger, former Italy international Antonio Cassano is convinced they will attempt to bring Mourinho back to west London.
Mourinho enjoyed his greatest success outside of England with Inter Milan, winning the treble with the club in 2011. With current Nerazzurri boss Simeone Inzaghi also under pressure, Cassano feels Mourinho would be tempted but would ultimately wait for a return to England.
‘If Inzaghi were to be fired, I would rule out the return of Jose Mourinho. If an offer from the Premier League were to arrive, the Special One would choose England,’ Cassano told Bobo TV.
‘The fans fell in love with his attitude (in Italy), but he intends to leave, and for me, he can only go back to Chelsea.’
Mourinho meanwhile has threatened to talk legal action after being sent off for a third time this season in Roma’s defeat to Cremonese.
The 60-year-old was shown his marching orders two minutes into the second-half with his side going on to lose to 2-1 with Cremonese picking up their first win of the season to climb off the foot of Serie A.
The former Chelsea, Manchester United and Tottenham boss claimed he has been provoked into the reaction by the fourth official who spoke to him ‘in the most incredible and unjustifiable way’.
‘I am emotional, but not crazy. In order to react the way I did, something had to happen first,’ Mourinho said. ‘I need to understand if I can take any legal action. Piccinini gave me a red card, because unfortunately the fourth official does not have the capacity to understand what he said to me.
‘I want to find out if there is an audio recording. I don’t want to get into the fact that Serra is from Turin and on Sunday we are playing against Juventus.
‘For the first time in my career, a fourth official spoke to me in the most incredible way. It was unjustifiable. At the end of the game, I went to speak to them. Piccinini, who was the fourth official in the last game when I was sent off, told me to apologise to Serra. I told Serra he should have the courage to explain what happened, but he had memory problems.’
