One of the negative by-products caused by building a successful team is that the most prominent individuals within that setup will draw mass amounts of attention toward themselves.
It's a feeling that a club of Chelsea's grand size will be familiar with, and Oscar is the latest Blues star to fall subject to increasing transfer speculation. According to French daily Le 10 Sport (h/t talkSPORT), Juventus have joined Paris Saint-Germain in their admiration for the attacking midfielder:
He is under contract until 2017 but it has been suggested in France that PSG will test Chelsea's resolve with a summer bid of around £42m, or €50m.
Juve, though, are also weighing up a bid for the Brazil international after reportedly sending scouts to watch him in action during Chelsea's 2-0 victory over Galatasaray in the Champions League last-16.
The tag of "untouchable" or "off-limits" might be applied to many players among Europe's heavy hitters, but as we've come to know, football can make even the most unlikely of eventualities possible.
However, Oscar is the kind of flagship asset that Chelsea truly can't afford to let leave the club, boasting the potential to become the face of a new generation at Stamford Bridge, alongside several other rising young stars.
The Brazilian playmaker has already made 104 appearances for Chelsea since making his switch from Internacional in the summer of 2012, per Soccerbase, a superbly swift century considering he's still just 22 years of age.
And it's indicative of his importance to the club that Oscar should rack up those numbers in such quick fashion, because he's taken no time in assuming his spot as one of the Blues' most important players.
WhoScored picked the youngster for their Champions League team of the week following his performance in the second-leg victory over Galatasaray:
Chelsea's, or more specifically Roman Abramovich's deep pockets mean that the West Londoners are under no pressure to cash in when pressured by their European peers for talent. Even if a player desires a move elsewhere, Chelsea are that category of club that can afford to dig their heels in and simply refuse to budge when it comes to their resources.
Oscar's presence in Jose Mourinho's midfield is in fact so crucial that the Portuguese's decision in allowing Juan Mata to leave for Manchester United came as a clear indication of exactly where his loyalties lie.
Mata, an experienced Spanish international and World Cup winner, didn't hold the same playing potential as the boy from Sao Paulo, or at least not in Mourinho's eyes.
His performances have been especially effective in Europe:
Attacking midfield has become a thriving part of Chelsea's squad, with talents such as Eden Hazard, Andre Schurrle, Willian and the newly acquired Mohamed Salah all contributing to a very deep bank of talent, not to mention those currently out on loan.
And with that being said, it speaks highly of Oscar's pedigree that he's been able to hold down a first-team place with such comfort; he will only solidify that stature as he adapts to the Premier League.
A scorer and provider of great goals, the youngster has already assumed his spot as one of the crucial string-pullers at Stamford Bridge, and Chelsea need to ensure that remains the case for years and years to come.
