We toppled in-form Everton at the Lane last Sunday in arguably our best display of the season.
We then started well at league-leaders Chelsea on Wednesday night and Harry struck the woodwork before two goals in three minutes paved the way for Chelsea's 3-0 victory.
Now back in N17, we take on a Palace team experiencing ups and downs - including a recent win against Liverpool but a home loss against Villa on Tuesday - in a 3pm kick-off.
"We’re looking forward to playing in front of our fans again and getting that atmosphere going again," said the young striker, 11 goals in all competitions so far this term.
"Everton was the benchmark of how we have to play this season and hopefully we’ll go beyond that against Palace and keep improving.
"We were all disappointed at Chelsea but we can't dwell on that because there are important games coming up, starting against Palace."
Harry has certainly been putting in a shift in starting the last four Premier League matches and he's ready to go again.
"You have to be able to do it at this level," he said. "The games are coming thick and fast and you have to be able to handle it. It would be nice to get back on the scoresheet against Palace - that’s what I always aim to do."
