Will Addison didn't have long to ponder his first start for Ireland as an injury to Robbie Henshaw in the warm-up meant the 26-year old Ulster player was tossed into the fray at short notice. 

But that's the way the Cumbrian-born player - who is Irish qualified through his Enniskillen born mother - preferred it, as he told RTÉ Sport's Damien O'Meara after the game. 

"It was a real whirlwind but it's probably the way I'd like it. There's nothing to think about except what's coming in front of me. The preparation we do during the week fully prepares me to come into those situations. I was absolutely delighted. 

"I really enjoyed my opportunities. I've got a lot to work on. There was plenty of stuff that I didn't do well so I've got loads to go through with the coaches so I'll take this as a building block.

"My parents weren't over this time but luckily my girlfriend was here and that was great. I'm sure my parents will be over next time."

The versatile back joined Ulster from Sale Sharks in the summer and before he'd even played for the province, his eligibility to play for Ireland was noted. 

He trained with Joe Schmidt's squad in Australia, not long after he had signed for Ulster. 

Addison says he's excited to be part of Ulster's rebuilding project under Dan McFarland after their traumatic 2017-18 season. 

"I've had a great period with Ulster," he said. "We've a really good thing building there, I think Dan McFarland has come in and pushed us to another level. I think the building blocks are being put in there that we can really have some success in the next few years with the talent they've got there.   

"I had a taste of the (Irish international) environment in Australia when I had a couple of days training. You could see from the outset what's required of each player and the standards you're set as well. And once you meet those standards, you're in a pretty good place for the weekend."

While the win was ultimately secured, Ireland's performance left many observers underwhelmed with Argentina providing stiff resistance until the hosts found some breathing space in the final quarter. 

Addison acknowledges the messiness of Ireland's play on occasion but is quick to highlight the quality of Argentina in mitigation.

"If you look at that Argentina team and what they've done in the past Rugby Championship; they've been really standout at times," he said. "They beat Australia away from home, South Africa and they've really pushed New Zealand. So, they're looking like a top team at the moment. 

"It took an 80-minute effort. It certainly wasn't elegant at times but it's something to work on definitely."
