Jose Mourinho has played down suggestions that his Chelsea side can win the quadruple this season.
The Premier League leaders dispatched Championship outfit Derby County 3-1 on Tuesday to move into the semi-final of the Capital One Cup.
Just a few weeks ago the Portuguese was refuting the notion of his troops staying unbeaten for the entire league season, before defeat at Newcastle United ended that prospect.
"We spoke a few weeks ago about being unbeatable in the Premier League and we never did it," he told BBC Sport.
"Now we speak about the quadruple but we haven't done it. We have our feet on the ground."
The West Londoners will face Paris Saint-Germain in the last 16 of the Champions League in February, while an FA Cup clash with Watford beckons next month.
