USA coach Gary Gold was quick to praise Ireland after their 57-14 win over the Eagles at the Aviva Stadium in Dublin on Saturday night.
Joe Schmidt's side ran in eight tries to finish the November series unbeaten after the Ireland Head Coach made 14 changes to the side that beat New Zealand last weekend.
Andrew Conway starred, scoring a hat-trick, as Ireland's second string put the visitors to the sword.
Speaking afterwards, Gold was keen to praise the home side and vowed that his team would learn from the experience, saying: The challenge is that there's not too many weaknesses. They've got a great set-piece, they've got a very good attacking game. They've got 10s, you know you leave Johnny out and you bring Joey in and even the guy on the bench is not a shabby 10 when he can come on.
"Their attacking shape is very good. Their skill-set is extraordinary - they're very clear in how they want to play the game but they're good enough to be able to execute it and on the other side of the ball, they work incredibly hard.
"I think probably in World Rugby at the moment, they're probably the team - through the analysis we've seen - who can look after the ball for the longest period of time and at half-time, we had five sets of play that went on for more than two minutes and one of them was three minutes, 20 seconds - I mean that's a lot of rugby.

"Unfortunately we knew we were going to learn lessons today and unfortunately at times, we weren't able to handle that pressure but that's only out of credit to Ireland - It's no shame on us, I don't believe," he added.
All attention now turns to whether Joe Schmidt will stay with the national side after the 2019 World Cup in Japan and he confirmed after the match that we will know by Monday of his plans.
