Chelsea are on a roll.
It will have been 15 games, over two months and 70 days come Saturday since they last suffered a defeat in any competition.
Mark Feb. 15 in your diaries, however. It's the day when the Blues' run will come to an end.
According to the report, the Chelsea boss plans on giving the likes of Mohamed Salah and Andre Schurrle starting berths, resting Ramires, Oscar and the in-form Eden Hazard.
The FA Cup match-up with City is a big part of that run-in, though. There's much more than a quarter-final place at stake at the Etihad.
City will be looking to get one over on the Blues after they were humbled last week with Branislav Ivanovic's excellent goal bringing to an end their unbeaten record at home in the Premier League.
Indeed, it's been a frustrating fortnight for City and Chelsea should be looking to make it worse.
When a rival is down, those around them should look to compound the misery. By knocking them out of the FA Cup, Mourinho will add to their woes.
By fielding a much-changed line-up, it will severely hamper Chelsea's chances to do that. And should City win—or worse still, do so at a canter—their beaks will be up once more. Confidence will be restored and with the Capital One Cup on Mar. 2, the possibility of an unprecedented quadruple will be a realistic possibility.
Mourinho should be going to the Etihad sniffing blood, riling Pellegrini even more by reveling in another victory.
Besides, with each game Chelsea remain undefeated, the more their reputation grows—the more they win the psychological battle with their opponents before a ball has even been kicked.
The mindset of players counts for so much in the modern game and it's something Chelsea themselves have thrived off in the past. They cannot lose that now, especially with a little over two months of the campaign outstanding.
Mourinho has made a point of suggesting this Chelsea team, his little horse, isn't ready to lift the Premier League trophy just yet. They are ready for an assault on the FA Cup, however, and as history has shown, it's a trophy that can hold plenty of milk to feed a maturing foal.
