The Stamford Bridge star celebrated reaching the Europa League Final on Thursday before quickly focusing on today's trip to Manchester United and then the visit of London rivals Spurs on Wednesday.
The Spaniard said: "We have to get in the top four. We have to win these two games.
"We want Champions League football next season. After that we can try to win another trophy.
"There are two tough games ahead. Playing Tottenham is going to be like a final because both teams will be fighting for the same thing.
"If we can beat Tottenham it will be a big step forward.
"But before that we have to think about Manchester United."
