Chelsea have suffered some turbulent times this season and their season could get worse as they face some tough fixtures within the next couple of weeks.
Chelsea start a run of games that will see them play Manchester United and Manchester City with two Champions League matches against Barcelona inbetween.
Even though they have lost two of their last five competitive games, Antonio Conte will most likely field a heavily rotated side in this match.
Chelsea struggled to beat Norwich in the third round and they risk struggling here again with a much changed side.
Hull City are in trouble themselves as they sit just one point above the Championship relegation zone ahead of this match.
A long run in the FA Cup would help them build some confidence ahead of their survival bid.
The Tigers are actually a team on the rise and they secured a 2-0 win at Nottingham Forest in their last game – that means they have won 3, lost 3 and drawn 4 of their last ten games.
Hull have built together a good away form as they have conceded more than a goal in only one of their last 14 away games.
