Chelsea captain John Terry was relieved to overcome FA Cup opponents Wolves.
Terry admitted Burnley's shock FA Cup exit to non-league Lincoln gave the Premier League leaders a reminder not to suffer the same fate against Wolves.
He told BT Sport: "It was kind of a wake-up call that we didn't need."
The chance of winning a sixth FA Cup is something which appeals to Terry.
He added: "It's a massive part of the club's history. I've won it five times. The main thing today was to come here, play well and get ourselves into the next round."
