Monday night's draw away to Fulham has left the Blues in sixth place in the Premier League, behind both Tottenham and Newcastle, but Kalou is confident his side can overtake both clubs, as well as Arsene Wenger's men, to finish in third place.
"We have to forget about the Fulham game and continue to work hard because it’s still possible to get the third place.” Kalou told The Sun.
Chelsea face a gruelling schedule in the next few weeks starting with a FA Cup semi-final showdown at Wembley on Sunday against Tottenham.
The Blues then play the first leg of their Champions League semi-final against European champions Barcelona at Stamford Bridge, before heading to the Emirates to face Arsenal in the league.
Despite their relatively lowly position in the league currently, manager Robert Di Matteo is confident his team can qualify for next season's Champions League and pinpointed the games against Arsenal and Newcastle as crucial if Chelsea are to secure a top four finish.
“It’s good that we still have to play these teams." Di Matteo said
"It’s still in our hands.”
