This season Chelsea fans have been cursing at Jose Mourinho, begging him to start Juan Mata and to give the Spaniard more games, but based on form, why not keep playing Oscar?
The Brazilian midfielder has played 12 games so far this season, and granted he has no assists, he has scored five times for the reigning Europa League champions.
Playing in that hole behind the striker, the midfielder can fade in and out of the position drifting out to collect the ball before playing a sharp pass leading to an attack.
And this is one of the reasons he has more of an impact on a game than Mata, because with the Spaniard, his best position is in the hole behind the attacker, and Jose Mourinho can't simply stick him on the right because he's not that versatile to run at players and to make them commit, while with Oscar it's different.
The Brazilian can play on the left or right, make defenders commit, put a great cross into the box, and if none of these aren't working, he isn't afraid to go it alone and to try and make something out of nothing.
Mata has only played seven times this season, but does he fit in Mourinho's system? And should he be ahead of Oscar? As the former Valencia man has scored no goals and made one assist.
A perfect example of Oscar is the better option dates back to the Confederations Cup final, Oscar giving a brilliant performance for Brazil, having his part to play in two of the goals committing himself to challenges for such a lean player, while Mata was substituted just after half-time not really settling into the game or creating any chances.
But not only in the final, overall Oscar played five games in the Confederations cup grabbing two assists, and for only being 22 has cemented his name in the first-team.
Again in the Champions League this year, the 22-year-old has played five games, collected two assists and scored one goal, while the 25-year-old has played twice and scored no goals and got no assists.
You could say that last year Mata was a key player, and he was a new star for Chelsea who could create a chance out of nothing, and there is no doubting this, as last year he grabbed 29 assists, but again he was Rafa Benitez's main man, as we've seen that with other clubs Benitez has managed; Steven Gerrard at Liverpool, Wesley Sneijder at Inter Milan and Marek Hamsik at Napoli.
But with Mourinho it is different, he wants a player who can offer more, can play in a number of positions and can play on both sides of the field.
It's not the case that Mata isn't needed by or good enough for Chelsea, it is just that he doesn't fit in the manager's system and doesn't offer enough to push in front of Oscar, Eden Hazard or Andre Schurrle.
Yes Schurrle, even Ramires has a suitable role in the current squad, a wide man who has a lot of energy, remember in the FA Cup final against Liverpool, and the Champions League semi-final against Barcelona?
By the end of this season, Oscar will have gained so much from this season, and we'll see him get better and at that 2014 World Cup he will grow some more under Luiz Felipe Scolari, for he is still young, and by 2015 Oscar will be better than Mata.
