Quinlan is back in the Munster squad for the first time since suffering a dislocated elbow in the game against Connacht at the end of December and his return is opportune given the quality of the Aironi back-row including as it does international Josh Sole and former Munster number 8, the hugely popular and very effective Nick Williams.
Aironi may still be searching for their first League win but they've been close to the mark on several occasions here in Zaffanella and have of course beaten mighty Biarritz in Europen fare.
Last weekend, a solid scrum gave Munster the platform to launch their backline and they showed how effective they can be when they get good quick ball.
McGahan will be looking for more of the same this afternoon and if they can reproduce their Edinburgh form, the result will look after itself.
However if they revert to the form they displayed a few hours down the road three weeks ago, they could be in for a very long day here in Parma.
