The Portuguese have already dumped Manchester United out of the competition.
Rui Costa, the clubâ€™s sporting director, declared: â€śWe have our weapons and we fear no-one.â€ť
Costaâ€™s â€śweaponsâ€ť include Argentinian Nicolas Gaitan and Paraguayan striker Oscar Cardozo, and he added: â€śWe are not scared to play at home first.
â€śWe are ready for what it takes. Nowadays, playing at home in the second leg has less importance.â€ť
