Jose Mourinho will be expecting much more of his Manchester United side at Chelsea this season; compared to the disastrous outcome on his previous return to Stamford Bridge.
A 4-0 hammering may have somewhat dented the 'Special One's' ego upon his return his former club last campaign, as the Blues went onto to win the title the season after Mourinho's sacking.
That miraculous turnaround from finishing 10th to being crowned Champions in 2016/17 was brilliantly masterminded by Antonio Conte.
However, it's Mourinho who goes in with the upper-hand on Sunday - with his side four points ahead of Conte's side - after a very promising start to the season.
The Portuguese may be held in high regard at the Bridge, but those treasured memories will be put aside as Chelsea look to close the nine-point gap on the top of the table.
Conte may be coming under some pressure at Chelsea, having followed up on their league title success with a somewhat sluggish start which has already included three league defeats.
However, much is expected of Mourinho this campaign after another summer of heavy spending - and his acquisitions are helping United to bear fruit as they look to close the gap on Manchester City.
United hopeful experience will help
The gap between City and United may already be five points after ten games, but that shouldn't concern Red Devils fans too much - considering Mourinho's hat-trick of Premier League titles.
Only Arsene Wenger has equalled the number of league titles Mourinho has won - although the Portuguese boasts 25 trophies across his glamorous managerial career.
But while the United boss' counterpart at Stamford Bridge on Sunday may have masterminded a title success from the shambles the Portuguese left behind, Mourinho believe he's one trophy from greatness.
Mourinho: I need one more title
“I think that probably 25 trophies is the line that people made about a successful manager,” Mourinho said, per The Times.
“For some managers, they still need to reach one more trophy to reach that 25 level. Some others need 25 trophies to reach that level, some others need four, some others need 12, some others they need 15, some others they need 24.
"I have 25, but I still need one more [to go above the landmark]. So maybe when I win one more trophy than 25 I have a little bit of credit. But that’s not a problem.”
As it stands, Pep Guardiola is in a strong position to land his first Premier League title with Manchester City this season; having dropped points just once this campaign.
And Mourinho's biggest rival could be the one to dent the 54-year-old's record of winning the title during his second season in charge at each of the top clubs he's managed.
The pressure's on the United boss to prove he's one of the greatest. And there's no bigger stage to do it on than at Old Trafford.
