"I felt we dominated that first half, a lot of that was through how we defended as well as how we attacked - it's a message for our players that we can play at that level and create more opportunities", he said. Scotland troubled Ireland at the gainline and found space behind the defence with several well-aimed kicks, but still trailed the visitors 12-10 at half-time. Sexton was well marked otherwise, though. The injury forced Hogg to walk off soon after. Finn Russell read the play well to intercept Carbery's pass and race towards the line.
Sexton's understudy Carbery so almost fluffed his lines when throwing an intercept pass to Finn Russell, who raced on and popped off the ground for Johnson to score.
Ireland finished the half strongly though, to ensure that they went to the break with the lead.
Scotland mistakes: Although Ireland were guilty of making plenty of errors, Scotland had their fair share too, gifting Murray an early try following a defensive mix-up.
"I'm the attack coach, and we weren't able to get those two or three phases either to get in behind the defence or set up our set plays".
Greig Laidlaw kicked a penalty in the 62nd minute to bring his side back within striking distance.
"They will look to keep the ball for longer periods of time and put pressure on Scotland when they have the ball".
The game will be only Farrell's second Six Nations appearance.
"If we want to take the next step, it's games like this we need to win against quality opposition".
The try was a double blow to Scotland.
Conor Murray, Stockdale and Earls all crossed for Ireland, with Carbery shrugging off an intercept pass that led to Sam Johnson's try to set up his Munster team-mate Earls for the victor.
Sexton duly missed the conversion, but Ireland eased those frustrations with another quick-fire score.
