Ex Hearts striker Samuel Afum is hoping the peculiar nature of Hearts-Kotoko games will ginger the Phobians to go all out for a win on Sunday despite their unimpressive form.
The two glamorous clubs are writing the headlines in African football this weekend as they clash at the Baba Yara Stadium in Kumasi.
Hearts are pecked 11th on the Glo Premier League table and face a Kotoko side that is the only club yet to taste defeat this season.
Kotoko are unbeaten in Kumasi since May 2011 after falling 3-2 to Liberty Professionals.
But Afum who scored in both legs to claim a back-to-back wins for Hearts in the 2009/10 season believes Hearts can halt Kotoko but insists they must develop a strong character to sail through.
"The players must develop a strong character and be disciplined on the pitch," Afum told Ghanasoccernet.com.
The FC Smouha attacker remains optimistic about Hearts' chances under new coach David Duncan.
"I think Duncan has brought a new spirit into the team and I believe they can beat Kotoko on Sunday to help lift the club.
