Leicester's form really bad this season, very different from last season's. Their current standings ranking can also be the lowest ranking since 2018-2019, only 6 points away from the relegation zone position, this is a serious threat for Leicester, from who this season played in UEL, are now in the danger zone.
This win is helpful for them and they have two other matches to play. I understand that with the performance of Leicester City in this season, they will hardly to win both matches but at least they have 2 resorts than other clubs in relegation zone.
The biggest problem leading to the worse performance of this club this season is their defensive line. We know Vardy is still one of the candidates of top scorers in EPL, it indicates they actually have no problem in attacking line. But their defenders performed very poorly, they are already conceded 43 goals although they made 39 goals so far. This learns us something that having great strikers will be useless if that club has poor defenders. This is a big task for Brendan Rodgers as a coach, to improve their defensive line if they don't want to be relegated to the lower competition next season.
They have more problems with defense but in attacking system part, they have issues too. Vardy is older and he has less contributions for Leicester City. That affects their ability to score goals from counter attack because Vardy is a great player for that tactics with his speed. When there are issues in attacking system and they can not use goals to cover mistakes and weaknesses from defense, they get less points so it is reasonable to see they fall down too low on table.
