It would be a shame if Everton were relegated this season, they are a strong Premier League team who are often in the middle of the table, but unfortunately this season they have fallen very badly. however I think their chances of avoiding the relegation zone are very big and last week's result against Chelsea will certainly lift their spirits.
The next match against Leicester City will certainly be very tough for them but they still have a chance to win it.
When viewed from the last few seasons, it is most likely not difficult for Everton to come out of the relegation zone, but in the English League, the things can happen, the lower players are sometimes able to give a surprise, but as you say, that the results of the match against Chelsea are enthusiastic for them, if able to play consistently for the rest of the match
I think the victory that was won against Chelsea last weekend was the start of a revival for Everton, they must do everything they can to win the rest of the season to save them from the brink of relegation, against Leicester I'm sure Everton will be able to produce pawns again.
Leicester is a tough club, not easy to beat them, if Everton does not play cautiously and is unable to compensate, then Everton's chances are very small, the English league is quite different in the style of the game every club, even the lower-board club also plays investive, many large clubs are overwhelmed such a club, because they have no big responsibilities
So far we've known that everton is a big team, and even in the last few seasons everton has been known as a team that kills big teams in the English league, but in the this season we have actually seen things that are very different, we can even say that Everton this season is quite bad, their recent declining performance make that they are now in the relegation zone and most likely will play in the championship league next season, even though they have 5 games remaining but I think they will difficult to get out of the relegation zone.
The possibility of getting out of the relegation zone is very open to Everton, because they still leave some of the remaining matches, but what Everton has to do must play consistently, the remaining five matches can make them out of the relegation zone, because if they are able to win the remaining five matches, then they will collect 15 points
