Porto coach Sergio Conceicao admits reputations are on the line tonight at Liverpool.
Porto go into the second-leg of their Champions League tie 5-0 down.
Conceicao said: "Our championship tells us that we are the best defence and best attack and tomorrow it is important to be a consistent team.
"Liverpool were very effective and in key moments where we knew that Liverpool were strong, we have erred in one situation or another and we want to play a different game."
He added: "We are playing the eighth round, we know the result. There is no greater motivation because: first we have the logo on the chest, to wear the jersey and respect the history; then we are in the Champions League; and the third is pride in giving a different image."
