Porto boss Sergio Conceicao insists they will try to target Liverpool's weaknesses as they look to level up the imbalance they face on and off the field.
The last two meetings between the clubs, in 2018 and 2019, have seen the Primeira Liga side concede 11 goals and score just one having lost the home legs 5-0 and 4-1.
Conceicao said while little had altered in Jurgen Klopp's squad, his own side had undergone significant change.
'If we look at Liverpool's experience, since 2019 they have lost (Dejan) Lovren and (Georginio) Wijnaldum,' he said.
