Home advantage could play a huge part in Saturday’s Guinness Pro14 final between Glasgow and Leinster but the holders should plan to "pound the hell" out of the Warriors, says Eddie O’Sullivan.
Both teams finished top of their conferences and came through their semi-finals with relative ease.
Dave Rennie’s side beat Ulster 50-20, while the champions were never in danger during a 24-9 win over Munster.
They meet in Celtic Park in Glasgow at 6.30pm on Saturday.
"The battle at the weekend is very straightforward," former Ireland boss O’Sullivan told the RTÉ Rugby podcast.
"Leinster have to play a physical confrontational game and basically pound the hell out of Glasgow every chance they get.
"It doesn’t mean they can’t move the ball, it’s knowing when to move it. In a physical confrontation, Glasgow will struggle.
"The Warriors will have to take risks and if you are doing that under pressure you can come unstuck.
"I think if it was in Dublin Leinster would achieve [victory] but the fact that it’s in Glasgow means that Glasgow will play with that extra bit of strut that we know they love to [show].
"If you let them do it they can beat any team in the tournament."
