Tipperary can't afford to make too many tactical changes if they want to shock Mayo in Sunday's All-Ireland SFC sem-final.

That's according to Tipp legend Declan Browne.

The Premier claimed a historic Munster title last month, a first for the county in 85 years.

But The Rebels competed alongside Tipperary in Division 3 of the Allianz League this year while Mayo were in the top flight, albeit they would go on to be relegated.

Speaking on RTE's Game On, Browne says that even though Mayo will be a tougher test than Cork, Tipp must stick to their guns.

"It's going to be similar to the Cork game - it has to be," he said when asked how his native county would approach the game.

"There's no point in changing it mid-stream now - it works. This game is going to be played at a different tempo and we need to be ready for that.

"We started brilliantly against Cork, and that really scuppered them. We were three or four points ahead and really got in their faces. Cork didn't know what to do, they didn't seem to have any Plan B.

"But that's not going to happen on Sunday.

"With (Paddy) Durcan, (Leeroy) Keegan, (Kevin) McLoughlin running they'll break through any walls and they'll be gone by the time you set up defensively."

Paddy Durcan is a key runner for Mayo

The counties met at this stage four years ago, with goals from Jason Doherty and Conor O'Shea helping the westerners to a five point win.

David Power had success with Tipperary at minor level, guiding them to an All-Ireland in 2011, before taking over at senior level last year.

He has brought former Dublin defender Paddy Christie on board in his backroom team, and the pair were able to come up with a plan to stop Cork runners at Páirc Uí Chaoimh in the Munster final.

For Browne it's about the Tipperary players keeping their heads and being able to follow their own gameplan if they want to stay the pace with Mayo.

"The big thing for me is that we don't panic," he continued.

"We should have our homework done, and I think David Power will have his homework done. Paddy Christie will have them set up defensively as well.

"The key is that we don't deviate from what we want to do, and that's to get the good lads up front on the ball.

"We've only played Division 3 and one Division 2 team (this year) so are we up to this level? Cork were poor, so are we ready for a battle, for a game at this level?

"I think that if we are then we're in with a good shout."
