Last season's Premier League Golden Boot winner opened his 2016-17 account in Saturday's impressive 4-0 win at Stoke.
Rewind 12 months, and the striker went seven games before scoring his first in the Premier League in the 4-1 win against City on September 26.
Two years ago, he didn't score his first Premier League goal until November - his first in the Premier League for Spurs. That was at Villa on November 2 - a goal he says he'll never forget - and by May, he'd scored 31 goals, 21 in the league.
"It’s actually the earliest I’ve ever scored in the Premier League!" said Harry.
"Okay, people are going to talk, people will say ‘he can’t do it again’ but everyone knows what I’m like, I’ll keep getting into the positions to try to score.
"I did that again but there were a few occasions where the ball just didn’t drop right for me. You keep going, especially as a striker, keep getting into the positions and I scored in the end."
As it turned out, his 50th Premier League goal was arguably his easiest!
He joked afterwards that he'd never been so pleased to see a team-mate miss the ball in front of goal! "Those are the best goals!" he said. "As a striker you wait for those chances and Eric Dier doesn’t need to score them!
"Thankfully, I saw it early and that helped, I knew I had time to control it and finish. I’m happy to score, every time is a great feeling and right in front of our fans. I'm delighted."
