We were in charge from the first whistle to last, carved out our first chance inside 60 seconds and could have won more handsomely than the 2-0 final scoreline.
Rafa van der Vaart opened the scoring from close range midway through the first half and Kyle Walker wrapped up the three points with a free-kick to remember from 30 yards in the 75th minute.
Sandro and William Gallas also struck the crossbar in an impressive first half display as we moved back into fourth in the Premier League with three matches remaining.
"I thought we were great in the first half, the passing and movement was fantastic," said Harry.
"We started well, got on top from the first whistle, could have scored in the first minute and dominated from there.
"We only came in 1-0 up at half-time and in all honesty, it could have been three or four. We are like that at home though, we can rip teams up. A lot of teams have come here and struggled to live with us."
The weekend's results mean that if we win our final three matches - Bolton away on Wednesday, Villa away on Sunday and then the final match at home to Fulham on Sunday, May 13 - we'll finish in the top four.
"It’s going to be close," added Harry. "We’ve got two really hard away games this week, Bolton are in good form and fighting for their lives and then we go to Villa, who probably still need a result.
"We’ll see how we go. If we win the games no-one can finish above us, that’s the top and bottom of it."
Meanwhile, Harry confirmed that Scott Parker missed out with a sore Achilles. "He tried training (on Saturday) and he couldn't play."
