Haroub, dubbed Cannavaro at his homeland, admitted that the Tanzanian champions are facing an uphill battle, but still sees room for recovery in Dar Es Salam.

"It will be a do-or-die match, I hope we will revenge, we just have to be focused," Haroub was quoted by local newspaper the Citizen.

"It is tricky to score four past the champions, but we are determined to recover the goals."

Gone

In the same manner, striker Mrisho Ngassa vows to do his best in order to help the African minnows grab an unlikely win over the six-time champs in two weeks time.

"Our opponents are determined to oust us, so we have to train thoroughly otherwise we are gone," said Ngassa.

Yanga were up against a similar situation in their last Champions League appearance in 2007, when they were trailing Tunisia's Esperance by three goals, followed by a goalless home draw.
