After victories over Meath and Kildare, O’Shea urged his team to keep it tight at the back against the Connacht county.
“I know it’s a cliché but goals win games, so we will do everything we can not to concede a goal. If we do that then it will give us a big chance, ” O’Shea said.
“At the other end, our forwards must make the most of their opportunities and penalise the opposition as much as possible.”
With the Kerry starting 15 likely to go along the lines of the team that defeated Kildare (1-20 to 3-12) in the semi-final, O’Shea is also expecting a big challenge from Roscommon.
“Any team that gets to an All-Ireland final and is trained by Ollie Canning will be very good. They had good wins over Donegal and Armagh so we know how tough this will be,” the Kerry boss said.
Full of praise for his own charges after they bounced back from heavy Munster MAHC defeats by both Tipperary (6-21 to 0-11) and Cork (6-22 to 1-4), O’Shea feels Kerry hurling might be better served, in future, by perhaps entering the Leinster minor league like Antrim did this season.
“That would be of a great benefit to Kerry,” O’Shea said. “The training and preparation we did for the Munster championship was actually of more benefit for us than the games themselves because losing heavily just knocked the stuffing out of us for a while. It serves no purpose for us to get beaten like that year after year.”
