The England U19 striker has set himself a target of earning his first Premiership start this term.
"I just want to get in the team and play more," said Delfouneso, who agreed a contract extension earlier this month.
"I want to become a regular. That's my next goal.
"It would be my main target to get my first Premier League start and after that it's got to be my aim to try to start at least five Premier League games this season."
