Cape Town - Chelsea midfielder Nemanja Matic says his side's next two games provide an ideal chance to restore confidence in the defending Premier League champions.
Chelsea succumbed to a Steven Naismith hat-trick at Goodison Park to leave the club just above the relegation zone.
The Serbian midfielder gave his side a glimmer of hope against Everton to pull the deficit back to one goal but Naismith wrapped up the match when he completed his hat-trick.
"Of course we are not happy," Matic told the club's website.
"Everybody is sad because of the result. Obviously we feel bad. We are in a difficult moment, and having four points after five games is not normal for our team.
"If you saw this game, I cannot say we deserved to win but we deserved a draw.
"Chelsea are not used to being on runs like we are at the moment but this is the reality. We have to work hard to get our game back to the way we played last season.
"I really don’t know what’s happened but it’s not good for us and we need to see what we can do better as a team."
Chelsea face two important matches in succession with Wednesday’s Champions League game against Maccabi Tel Aviv at Stamford Bridge before Arsenal arrive on Saturday in a crucial Premier League clash.
"It’s good we have another game in a couple of days against Maccabi," added Matic.
"We have to win, for our own confidence and for the fans. Then we have a derby against Arsenal, so I hope we will be ready for that and we can take three points."
