With coach Carlos Queiroz missing because of a ban, the usually solid Portuguese defence conceded four goals in 90 minutes, having let in just one in four matches at the World Cup.
"We need to be more compact and to play more as a team to win in Oslo," said Carvalho ahead of the Group H match.
"There was a lack of competence in a defence which is normally competent," said Oliveria, who is without forward Cristiano Ronaldo because of an ankle injury.
"This defence is solid... I find it hard to understand and accept this result."
Portugal's experienced central defensive pairing was at fault in two goals, Bruno Alves and Ricardo Carvalho looking slow and out of synch.
Miguel lacked pace but is now Portugal's only solution at right-back as Paulo Ferreira has quit the side and Jose Bosingwa is out injured.
Options for left-back are also scant after Fabio Coentrao was ruled out of Tuesday's game with a thigh injury. Braga's Silvio may earn his first cap, though midfielder Miguel Veloso can also fill the post.
Abdealloue scored the winner against Iceland and his pacy style could fit Olsen's strategy perfectly.
"The draw with Cyprus tells us the Portuguese team does not know how to deal with counter attacks, and that can be good for us," Norway coach Egil Olsen said.
