Both teams are in a bad season, Leicester is even worse they have suffered 15 defeats and that is the second most after Southampton in the season, Leicester are still in question whether they can end this season without being relegated because their points are not much different from the teams that is below them, so this should be a balanced match, meaning that all possibilities can happen that the host wins or Chelsea wins or will end in a draw.
Chelsea should be concerned about is how they can score goals, this is their main obstacle, while Leicester's main obstacle is their poor defense if Chelsea get this opportunity they have a chance to win and maintain their position in the top 10.
Leicester was a bit better compared with chelsea. you can't take the overall performance during the season as a measurement to determine which team that was even strong. Afaik, leicester has worst record for this season compared with chelsea but leicester was not buying so many players crazily like chelsea. Leicester was using using what it has in the past. Vardy was too old and his performance declined so hard. Chelsea may use the same formation like when chelsea faced leeds united last week.
Chelsea was not even able to make goal from the team work. The goal that happened against leeds was coming from fofana. Chelsea's team work is still very bad overall.
If potter will not change its compositions and im sure that the result against leicester city gonna be even worst compared with leeds. Draw or lose.
