Chelsea goalkeeper Petr Cech is delighted with their progress this season.
Chelsea play at Sunderland in the Capital One Cup on Tuesday night with a place in the semi-finals at stake.
Cech said: "It's great to be in the position we're in: we topped the group in the Champions League, we're two points off the Premier League leaders and we can be in the semi-final of a domestic cup if we win on Tuesday.
"All of this, and we know that we haven't reached our peak, so it's great."
