Chelsea head into this extra fixture with only one thing in mind – a first win in 4 games.
The Blues have been underwhelming recently and their failure to win any of their last four games has seen Liverpool leapfrog them into 3rd place in the Premier League and added this FA Cup replay to their already busy schedule.
They were lucky not to lose to Leicester City at the weekend despite their visitors being reduced to 10 men.
At the moment, the Blues are very blunt on the attack and they desperately need a win to boost their morale.
If Norwich secure an unlikely win in this game, that could the beginning of the end for Antonio Conte.
Chelsea remain unbeaten in their last ten games, but have won only five of those matches.
Norwich head into this game unbeaten in their last five games but their poor run of form between November and December means they are still 13th in the Championship.
They have 3 wins from their last 5 competitive games but where the most improvement has come from is their defence as they have conceded only once in their last 5 and are currently on a run of 3 successive clean sheets.
Although their chances of keeping another one at Satmford Bridge is low, Chelsea’s poor form in the final third makes it very much a possibility.
