Ireland head to Paris to face France in search of a Six Nations title, and it will be a tough assignment, according to the Against The Head panel, with Eddie O'Sullivan singling out the absence of Garry Ringrose.
On Monday it was confirmed that Ringrose will miss the rest of the autumn international window after sustaining a broken jaw in last weekend's win over Italy in Dublin.
"Ringrose is a big loss and that's going to change our dynamic," was O'Sullivan's reaction when speaking on Against The Head.
"He does bring that cutting edge at outside centre and he's a line breaker. He's on top of his game, very unfortunate."
In looking ahead to Saturday's clash at the Stade de France, the former Irish coach singled out one player.
"Jacob Stockdale has more in him. He's a big, big man, very quick and if he is not going to make a line break, the fact that he goes into contact so aggressively, he gets you on the front foot."
In casting an eye over what might transpire against France, both Fiona Coghlan and Donal Lenihan were of the view that the Irish will have a job on their hands in dealing with the physical challenge.
Coghlan summed it up when saying: "Over the years they haven't been sure who their half-backs were. Now they have Romain Ntamack and Antoine Dupont. The whole team is built around them.
"They also have the forwards. It begs the question whether Ireland can face the physicality they can bring, allied to what their forwards will offer. It's a different beast next weekend."
Commenting further on France's improvement, Lenihan added: "When Ireland have come up short before, it's against those big physical forwards.
"France are now a way more fitter and athletic than they were two years ago. Cyril Baille and Mohamed Haouas, the two props, are brilliant carriers. Bernard Le Roux may be cited but he's an outstanding forward playing in the second row.
"He has a big lump next to him in Paul Willemse. They play him for 50 minutes and then they bring on Romain Taofifenua. So there is athleticism within that French pack. The bench is very strong. Camille Chat, the outstanding Racing hooker, is held in reserve."
