Excitement is building ahead of Donegal and Tyrone's clash at Ballybofey and the players are no different when it comes to looking forward to a big game.
Newstalk Breakfast's Oisin Langan caught up with Tyrone's Sean Cavanagh.
Surprisingly the four-time All Star said that "everything points towards a Donegal victory," because of their Championship form over the last two years and the home advantage that they will enjoy."
He also felt Jim McGuinness' influence would be crucial for the opposition, comparing the Donegal manager to Jose Mourinho at Chelsea.
Despite a strong league campaign, Cavanagh sees Tyrone as underdogs which he feels is a good position to be in.
"League and Championship form are completely different and on Sunday we'll need to be of a higher standard than any of the league games we were in."
