Ciarán Frawey says his match-winning dropgoal to beat South Africa is the best moment of his career, even if he admitted it was the "ugliest" strike of his life.

The Leinster out-half made himself the hero of Durban, landing a drop from more than 40 metres out to see Ireland complete a dramatic 25-24 comeback win against the world champions.

Twelve minutes earlier, Frawley's instinctive drop at goal had brought Ireland back within a point of the Springboks to give them a sliver of hope in a game they looked destined to lose.

But with the final moments of the game, he showed remarkable composure, firstly to perfectly weigh a grubber kick down the touchline which forced the Springboks to carry the ball into touch, before putting the team on his back to deliver the winning points.

"Definitely, definitely," Frawley told RTÉ Sport, when asked if it was the best moment of his career.

But the 26-year-old had to laugh as he looked back on the winning score.

"The strike was probably the ugliest dropgoal I've ever hit in my life.

"The one in Tottenham [in the Champions Cup final] was way better, which is funny. It worked out, which is key.

"Bladey [Caolin Blade] pulled the trigger at the right time. They were probably expecting us to pick and go a little bit more and get better field position. I felt there was no pressure on me when I went for the dropgoal.

"I hit it so ugly that it was on the left post, so I knew it would come back to the right. I was more just telling it to go, get over! The ref was looking at it as well.

"When they called it back for the TMO check, I was like 'Oh, God. Please, no!' but I'm just absolutely delighted, It's a proper way to finish a Test series."

Frawley kicked the drop with the final play of the game

The most impressive element of the dropgoal was that Frawley engineered the field position to attack with a risky, but perfectly weighted kick down the line which was carried into touch by Cheslin Kolbe.

Had that kick not been perfect, they wouldn’t have had the chance to even attempt a dropgoal.

"Sometimes it can be instinctual but you definitely see the picture. We got caught in that game of kick tennis and I felt the minutes were passing by.

"The lads put in a massive shift but there was a lot in the legs and we just felt like field position was the right thing at the time. It was probably the 79th minute when we put the grubber kick through.

"It was an unbelievable kick chase by Lowey [James Lowe], he puts him out, we get the chance for a dropgoal.

"The clock was actually hard to find in the ground so myself and Caolin Blade were having a bit of a discussion.

"There was something going on before the lineout so Bladey actually saw the clock was close to being in the red and we put our heads together and said this lineout we'd work it, so a lot of credit to him for using the head. We just got ourselves into the right position, right play, and executed it well," he added.

In may ways it was appropriate that the Leinster man’s dropgoal heroics saved the day for Ireland, after he missed a game-winning attempt for Leinster in the Champions Cup final against Toulouse in London back in May.

"Especially after Tottenham against Toulouse. I was delighted to see it go between the posts.

"It's the way the game goes sometimes, you get injuries along the way and little setbacks. I've been jumping around positions and stuff like that, but I've been training a lot at ten and training a lot at 15 and 12, but stepping in there isn't alien to me.

"I felt confident when I came on, I felt the lads around me gave me a great buzz. It's just executing off the back of it which felt quite instinctual," Frawley said.
