Chelsea face an FA Cup replay against Norwich after producing a largely listless display in a 0-0 draw at Carrow Road on Saturday.
The Premier League side, who reached the final of the FA Cup last season, created few chances of note after making nine changes to their starting line-up.
Their best openings came in the second half as Danny Drinkwater shot wide from near the penalty spot and Willian saw an effort turned past the post by Angus Gunn.
Championship side Norwich rarely threatened themselves but will be more content with the result than Chelsea, who also face Arsenal in the two-legged semi-finals of the Carabao Cup over the next few weeks.
The replay at Stamford Bridge will take place in the week of January 15. Chelsea set the tone for their below-par performance in the first half when they regularly gave the ball away and failed to trouble Norwich goalkeeper Gunn.
The hosts looked comfortable in defence and also created opportunities, with Josh Murphy dragging a shot wide from inside the box and James Maddison firing over the bar late in the half.
Chelsea did improve after half-time, with Willian injecting some much-needed pace and drive around the box. The Brazilian saw a couple of shots saved by Gunn and also picked out Drinkwater with a low cross from which he fired wide.
But Norwich managed to stem the tide and Alex Pritchard shot over in a rare second-half opening for the hosts. Chelsea pressed late on but the closest they came to a winner was when Davide Zappacosta shot narrowly wide in injury-time.
