Owen, who was an unused substitute for the final, is raring to go ahead of the trip to Benfica as he awaits his first involvement of the new campaign.
"If we played Barcelona again in the final, then we'd have to do something differently because they obviously outplayed us on the night," he explained to Inside United, the official club magazine.
"Then again, I don't think there's any shame in losing to a team like that. We're not ashamed of how we played at Wembley but, if we played them again, then I do think we'd have to look at adopting a slightly different approach.
"On that one night's evidence, you'd have to say that there was a gap between the two sides because they beat us quite convincingly. But that was a one-off game. We wouldn't be frightened of playing them again, that's for sure."
