Kumasi Asante Kotoko have been warned by Alhaji Grusah to be wary of Kenya side, Kariobangi Sharks in the second leg of the CAF Confederation Cup on Saturday.
Kotoko will face Sharks in the preliminary qualifying round second leg tie after the first leg ended in a goalless draw in Kenya.
Following the result, the Kenyan side will be seeking to win or minimally, attain a scoring draw which will guarantee their progression to the next stage of the competition.
The King Faisal bankroller told Kotoko to prepare meticulously and urged the Porcupine Warriors not to underestimate the Sharks.

"Kotoko is not guaranteed an automatic victory in the game on Saturday so they should prepare well and their supporters need to lower expectations," Grunsah told Goal.
"Kariobangi Sharks may not be the biggest or strongest club from Kenya but they can cause a major upset if they are underestimated. Any goal from them in the second leg can bring pressure on Kotoko so they must be very careful not to concede at home.
"Even if they will concede a goal, I believe it should be a consolation since that can't affect their ambition of making it to the next round. Kotoko must make Ghana proud by trying their best to avoid a shock and make it to the group stage, " he added
