The two sides are set to do battle in the group stages, with Porto hoping to improve on a dismal recent record against the Reds.
"If we look at Liverpool's experience, since 2019 they have lost (Dejan) Lovren and (Georginio) Wijnaldum," Conceicao said ahead of Wednesday's clash at the Estadio do Dragao.
"We were left with three: (Jesus Manuel) Corona, Otavio and Bruno Costa.
"That experience and the fact that they stay together is very important in a competition like this.
"We can highlight numerous theoretical differences, such as the fact that our budget is 20 or 30 per cent of Liverpool's, but that will not come into play tomorrow.
"What comes in is the preparation of the game, the strategy we define and the way we are going to be organised.
"It's up to us to counter that opponent's power and expose some of the opponent's weaknesses, because they also exist."
