Aluko came off the bench on Sunday to help Hull beat Sheffield United 5-3 in the FA Cup semi-finals, and the 25-year-old now hopes that manager Steve Bruce will give him more chances to make his mark.
The Nigerian told the Hull Daily Mail: "If you are not playing in the league or in the cup games, then pretty much you are not playing at all and you start thinking, 'Is this for me? Do I need to find a new club?'
"It does go through your head, so it was important for me to come on and make an impact. It was good to show the manager what I can do and hopefully it bodes well."
Hull's Premier League campaign continues on Sunday at home to Arsenal.
