Oscar admits Chelsea's season will be decided next season.
Then they host Russian outfit Rubin Kazan in the Europa League next Thursday before facing Sunderland three days later as they bid to hold on to a Champions League place in the top four.
Oscar said: “It is a week that could be really important for our season.
“We just have to play and rest as best we can. We always have a lot of games, though maybe four in a week — as we have this week — is a bit different.
“There are so many games at the moment, and all of them are important.”
