The Portugal coach is keen for his team to pay close attention to what their World Cup play-off opponents do best and brands Cristiano Ronaldo the best player in the world
The two-legged World Cup qualifying play-off between the European nations has been billed as a battle between Ibrahimovic and Seleccao forward Cristiano Ronaldo.
Ahead of the first leg in Lisbon, Bento has warned his side that they cannot afford to simply focus on the Paris Saint-Germain superstar but acknowledged the Swede's obvious talent.
"Zlatan Ibrahimovic is a great player, he's also in a great moment with his club. He is extraordinary," the Pirtugal boss told a press conference on Thursday.
"For us, to try and stop this player we have to make a collective effort and not just be aware of the individual. We need to understand the organisation of Sweden and, on the top of everything, play our game."
Bento also talked up the ability of Real Madrid forward Ronaldo, defending his record for Portugal and insisting that he deserves to take home the Ballon d'Or.
"I think it is natural that sometimes the performance is not the same for the national team compared to the club," the 44-year-old added. "Right now, he is exceptional. With us, some time ago against Northern Ireland [in September when Ronaldo struck a hat-trick] he was sensational and we count on his skills and motivation.
"We will have to be organised and with this he can play in the same way he is playing for Real Madrid.
"Maybe at other times it would not be a fair win but it would be unfair for Ronaldo not to win [the Ballon d'Or] this year. Right now he is the best player in the world."
