The Canaries held the Premier League champions to a 0-0 draw in the original tie, keeping them in contention for a Fourth Round home game versus Newcastle.
However, having lost six and won none of their last seven matches at this ground, they are 11/1 (12.00) outsiders with Paddy Power to make it through to the next stage with a surprise victory here.
That stalemate was a fourth in succession for the hosts, and there are odds of 5/1 (6.00) on offer on this game going into extra-time after another deadlocked 90 minutes.
Conte is likely to pick a similar line-up to the reshuffled side he fielded in the original tie, although new signing Ross Barkley is unavailable as he was not registered on time.
Opposite number Daniel Farke is also expected to stick to the same XI, although Alex Pritchard will have to be replaced after leaving to join Huddersfield Town.
Another tight game
Chelsea need a creative spark as they have just played out three consecutive 0-0 draws for the first time in their history, and will likely turn to Willian and Pedro to provide it in the absence of many regular first teamers such as Eden Hazard and Cesc Fabregas.
The out-of-form Alvaro Morata will sit this replay out, and although Michy Batshuayi is clearly unfancied by his manager and looks set to leave the club this month, the Belgian will lead the line against a Championship defence that has conceded just a single goal in the last five games.
On the other hand, the Chelsea backline that has kept seven clean sheets in the previous nine games should not have too much difficulty at the other end of the pitch, considering Norwich have scored just six times in seven matches themselves.
Tips and Predictions
All in all, odds of 6/5 (2.20) offer excellent value on under 2.5 goals being scored for the fifth meeting in seven between these two teams.
