The Blues have games across three competitions starting with a Premier League trip to Southampton on Saturday, and by the time they take on Sunderland nine days later they will have also played Manchester United in an FA Cup quarter-final replay and a Europa League quarter-final first-leg against Rubin Kazan.
Oscar admits this kind of fixture pile-up is new to him, but he is looking forward to it and feels each of the four games is vital in their aim to end the season in a positive manner, and possibly with some silverware.
"There are so many games at the moment, and all of them are important," he said.
"We have Southampton first and then Manchester United 48 hours later. But that is the way it always is at a club like Chelsea. We always have a lot of games, though maybe four in a week - as we have this week - is a bit different.
"We have to play and rest as best we can. It is a week that could be really important for our season. We have games in all three remaining competitions, but we're not thinking that one could be more important than the other.
"We want to win all of the games and we want to do as well as we can in all the competitions. We won't sacrifice one for the others."
