Aberdeen manager Craig Brown says he will urge his side to heap added pressure on struggling giants Celtic.
The Hoops, 10 points behind Old Firm rivals Rangers, have already dropped three games this season and had to fight hard from three goals down to force a 3-3 draw with Kilmarnock on the weekend.
Brown senses some vulnerability from Neil Lennon's men and is hoping his Dons outfit can push them all the way at Parkhead on Sunday.
"In light of Celtic's recent difficulties, we have the chance to go down there and get a result on Sunday," he said.
"There will be no fear from my players for the upcoming games against Celtic and Rangers. This is a chance for them to go and prove they are a good team.
"We have already performed well in Glasgow this season when we were unlucky not to take something from Rangers at Ibrox.
"Now we have to reproduce that kind of performance to make sure we take something from Celtic Park."
