"Sexton saw Zebo was free out wide there and the bounce was absolutely perfect.
"Zebo didn't even have to break stride there as he ran on to it and crossed over the try line."
Johnny Sexton may have just missed a kickable penalty for Ireland but he redeems himself immediately.
The Ireland fly-half identifies space down the left and his pin-point kick is picked up by the sizzling Simon Zebo to ssore. Great start from the hosts.

"A let off for Australia there with that missed penalty from Sexton and Ireland will be disappointed.
"When you get in to the opposition's half, you want to keep the scoreboard ticking over."
In full-backs Israel Folau and Rob Kearney we have two of the finest aerial exponents in the game - and the fact they played Australian Rules football and Gaelic football respectively is probably no coincidence.
The latter is taken out in the air by James Slipper but Johnny Sexton's penalty slips by the sticks.

"It just shows you the importance of precision.
"A loose pass from Australia saw them very quickly back-pedalling and ultimately giving away a penalty.
"There's just no room for error in international rugby."
Andy Burke
BBC Scotland at Rugby Park
"I think we can say the rugby at Rugby Park experiment has been a success. A good atmosphere, good surface and most importantly a good win for Scotland. The ghosts of Tonga's win at Pittodrie in 2012 have been well and truly consigned to history. The fans applauded their heroes off the park and now look forward to the Six Nations with more hope than they have had for some time."
Seamus Joyce:, external Ireland to lead start to finish and win by 8 points !
John McEnerney:, external This will be a belter! Ireland looking for a 2nd SH scalp & we are well equipped 2 do it but Aus have plenty of talent to undo us!
Munster blind-side Peter O'Mahony is already making his mark at the breakdown and he earns a kickable penalty for Johnny Sexton.
They do love a choke a tackle, do Ireland. Tevita Kuridrani makes a threatening break but is brought to halt by Simon Zebo.
When they switch the all into midfield the swarming Irish defence holds the ball up off the ground and earns a scrum for the hosts.

Michael Cheika took over as Australia boss in October after the departure of Ewen McKenzie following poor form on the field and further issues off it.

Scotland coach Vern Cotter speaking on BBC One: "The guys ground out a tough win and it wasn't easy.
"Very tight at half time and we did the simple things well in the second half.
"Our line-out was working well and it got us ahead.
"I think the game two years ago is like a monkey off our back and we can move forward."
Scotland's World Cup Pool consists of South Africa, Samoa, United States and Japan.
It is tough, but they should get through that. The last time they were in the knockout stages was in 2007.
Mike Blair
Former Scotland scrum-half on BBC One
"Vern Cotter has made sure the line-out is fantastic and that's been great in these last three games.
"You build your game around that and the work off scrum-half and it's been a great foundation for Scotland."
One of the main talking points concerns the two coaches, who will both be more than familiar to Dublin residents.
New Australia boss Michael Cheika guided Leinster to their first ever European Cup, while he was succeeded at the province by Joe Schmidt, now boss of Ireland, who took them to Heineken Cup glory twice.
