Bento will field a weakened team that has been hit by the absences of midfielders Joao Moutinho, Nani and Raul Meireles and forward duo Varela and Vieirinha.
As they look to build some momentum ahead of next month's World Cup Group F qualifier against Northern Ireland, Bento acknowledges the absences will have an affect on his side but is still confident they can claim a positive result against the Oranje at Estadio Algarve.
"Five changes from the initial call-ups always has some impact because they are players who have influence and dominance in a team," he said on Portugal's Football Association website.
"It's a situation that can create some difficulties, but that will not stop us trying to play a good game. We want to demonstrate competitiveness and these absences will not put that in question.
"That is what we instill in our players, who should be motivated to represent the national team and seize the opportunity that arises at this point.
Dutch winger Arjen Robben believes Portugal will provide a stern test as his side look for a victory that would give them some confidence ahead of next month's World Cup double-header in Estonia and Andorra.
He said in De Telegraaf: "It's a risky team lurking very much on the counter, whereas we have a team that wants to dominate.
"Defensively, physically and tactically, the players of Portugal are very strong. They play from good organisation."
