This summer, Chelsea's transfer policy has acted like a warning to those that played major roles in last year's trophyless campaign.
Despite the Blues already having numerous options in midfield, Cesc Fabregas has joined the west London side for a big-money fee. Diego Costa, too, has bolstered their front line, while rumours persist as to further Mourinho signings ahead of the new campaign.
Every deal, of course, has ramifications for existing players. Two under particular pressure are Oscar and Ramires, both attack-minded midfielders who have been on international duty with Brazil this summer.
Indeed, Fabregas' arrival increases the competition for both, while the likes of Eden Hazard, Willian, Mohamed Salah, Andre Schurrle, Nemanja Matic, Marco van Ginkel and John Obi Mikel already show how many options 51-year-old Mourinho has at his disposal.
Which of the Brazilian duo, then, has done the most to stake their claim at the World Cup?

As Opta stats show, the first key fact to note is that 27-year-old Ramires has played far less minutes than Oscar, despite the pair making six appearances each. Whether that offers a hint in itself is unclear, though it blurs the statistics a little.
Nevertheless, looking at minutes taken per key actions, attacking midfielder Oscar comes off better in four out of six areas. Firstly, he has won more dribbles than Ramires, while also making more accurate crosses (Ramires made zero).
Interestingly, though, the 22-year-old also won far more tackles, taking half as many minutes to make one on average. That defensive ability is shown, too, with Oscar taking slightly less minutes per interception.
Where Ramires does come out on top is with his passing accuracy - shading the contest by three percent, while he also averaged less time between each successful final-third pass.
That makes it four-two in Oscar's favour - and that's without counting the fact that he has two goals and two assists to his name in the tournament. Ramires has one assist and no goals, although the fact that he played far less minutes does come into play here.
So who's had the better World Cup of the two? It has to be Oscar. What that means for Ramires' place in the Chelsea team is, again, unclear. But the signs are more likely to be bad than good for the Brazilian.
