Gareth Bale broke into the box on the left, sped past Joleon Lescott and squared low for Jermain rushing in at the far post, goal at his mercy.
It was like slow motion as Jermain slid in to reach the cross but he couldn't quite get there and ended up squeezing the ball just wide with his outstretched boot.
To pile on the agony even more, City's final attack in the fourth minute of added time led to Ledley King bringing down Mario Balotelli for a dramatic late penalty.
Balotelli made no mistake from the spot and a game we could have won slipped away.
"We showed real character to come back and then had that great chance at the end," reflected Harry.
"Gareth rolled the ball square to Jermain and we were all up on our feet ready for the ball to be put into the empty net.
"But he couldn't quite get there. He changed his stride pattern slightly and missed it by inches.
"They then got the ball forward, it was a bit of a melee and the penalty came from that. It was heartbreaking to lose like that.
"I couldn’t have asked for any more from the players.
"We came in at half-time at 0-0 and I thought it was evenly balanced, we kept the ball wel and passed it great.
"We then had a bad two or three minutes when we conceded the two goals.
"We came back and looked the more likely to go on and win it at 2-2.
"It was so frustrating in the end but I was delighted with the players."
After battling back from 2-0 down to level at 2-2, we carved out a match-winning opportunity in the first minute of added time.
