He believes both sets of front five forwards have developed during the tournament to set up a fierce encounter.
McBryde said:”Their front five have certainly proved their worth as a scrummaging unit and the back five are then working so well that their back row has more freedom around the field.
“The quarter final will be won and lost up front.
“We can only focus on what we can control but our front row have a bit of a reputation of their own and we have certainly got a combative back row as well.”
The Welsh forwards coach believes the inclusion of Rory Best at hooker for Ireland is a big boost for them.
“Best is a very combative forward so it will be a big plus for their coaches to know he has made it onto the field,” said McBryde.
He praised the Welsh squad for how they had developed in rugby terms and mentally as the tournament has progressed.
He explained: ”At half time against Namibia and Fiji we could have taken our foot off the gas but a mark of this Welsh team is that we finished the job off.
“When you couple that experience with the arm wrestles we have been in with South Africa and Samoa we’re in a good place. We have learnt quite a bit about ourselves in the last month.
“The youth inour team is setting the standards right now. They play what is in front of them which means if there’s a gap they go for it. They want to go out there and play rugby.”
He promised that if the expected sunshine keeps the weather good in Wellington the fans could be in for a spectacle of rugby from both teams.
“We are told the sun is going to stay out through the day so we are looking forward to the game,”he said.
On Friday the Wales team had a run out at the stadium in Wellington as part of their final preparations for the clash.
The city which hosts Wales v Ireland and South Africa v Australia in quarter final encounters over the weekend was beginning to swell with fans as the games approached.
