Fulham have been on a fantastic run of form, having won five of their last eight, and are within touching distance of the top six.
The Cottagers, who sit in seventh place, are just one point behind sixth-placed Sheffield Wednesday, with three points the gap to Reading in fifth.
Slavisa Jokanovic's men missed an opportunity last time out when they were twice pegged back in a 2-2 draw with Blackburn Rovers but Aluko, who has scored six league goals this term, is confident the team will get back to winning ways.
"You have got to just take it on the chin," he said. "Confidence is still high and four points from our last two games is not terrible. It is not drastic so we will go again and we are still confident that we will make the play-offs. We would have taken it a few weeks ago."
Fulham return to action on Saturday when they host a Wolverhampton Wanderers side who are just four points above the relegation zone.
