Wright was in his native Belfast on Thursday night to watch Rosenborg come from behind to beat Crusaders 2-1 in the first leg of the first qualifying round. Jordan Owens gave the hosts a shock lead and they put the Norwegian side under pressure throughout.
Wright, who will watch Rosenborg take on Lillestrom on Sunday, told his club's official website: "Crusaders played very well and were unlucky not to get a draw.
"That said, Rosenborg rested five players who I feel would probably be termed as normally being in their starting 11 and I think I will get a better feel for them when I see them again on Sunday."
He added: "Rosenborg are a strong, powerful team and a different proposition from Eskisehirspor last season.
"I actually think the Turks were better technically but there is no doubting Rosenborg's quality.
"However, I've come away with the feeling that we can go into the tie with confidence."
