Cork manager Conor Counihan feels his players can cause a major shock on Saturday night against Dublin in the All-Ireland Football quarter-final in Croke Park.
The Rebels saw off Galway in the last round of qualifiers to set up a clash with the Dubs.
Counihan told RTÉ Sport: "It is a big challenge. They are the form team and big favourites and having won the National League and Leinster title in comprehensive wins, they are certainly the team to beat.
"We know that if we can bring our best game we are confident we can cause a bit of a surprise.
"Our performance in the first half against Kerry is something we would have been very, very disappointed about. The lads did play well in the second half, but we'd still be disappointed. We can't dwell on that too much.
"We had to get on with it and last Sunday against Galway was another step in the right direction.
"There is plenty of room for improvement and we're under no illusions that if we are to be victorious, we have to move significantly from where we have been during the year."
