"But you know what ? None of this should matter."
As far as O'Sullivan in concerned it will be a case of more of the same as the Italians try to beat-up the Irish, "attack Ireland today like mad dogs in a meat house," as has always been the case, a tactic Ireland should be well prepared for.
"People can parrot on about the power of Italy's scrum, but they were doing the same last year and it didn't make a whit of difference at Croke Park." he says while the area where'll they'll struggle will be at half back.
" So with Edoardo Gori and Kristopher Burton, who have amassed a grand total of six caps between them, starting today in Rome, Italy are extremely vulnerable. Going in to battle in the Six Nations with untried half-backs is like sending Columbus off in search of America without the benefit of a compass."
And you know what ? He's dead right.
And to understand the threat the Italian outside backline pose, ask yourself the question, what Italian players would you swop for those Irish today wearing numbers 11-15 ?
O'Sullivan believes that, "Ireland will do what they have always done. They will keep their heads during the onslaught and at some point (usually about 10 minutes before half-time) strike with a precision that leaves Italy hanging on by their fingernails for the half-time whistle.
Here's hoping he's right.
