Pulisic came off the bench in the second half of that 1-0 victory over Manchester City on 29 May and nearly two months later admits he is not used to his status as a European champion.
"The whole thing was kind of unreal," he explained to chelseafc.com. "I don't know, winning it has never really fully hit me I don't think. Maybe it will in more time. I think it will take me a couple of years for it to really sink in!"
It has not stopped him enjoying the memories of that night in Portugal, though, and he also believes the feel-good factor among the squad will carry over into the new season.
"It's just a really proud moment in my career, to be involved in a success like that. I think a lot of the guys will go into this season nice and confident and that's really important, and also everyone is hungry to win more which is the best thing you can have in the team. We all just want to keep on getting better."
