Missing the excitement of doing it in a particular match.
I mean like back when Ronaldo was still with some great players joining Madrid and Messi was also still with Barcelona, we always looked forward to the exciting competition in every El Clasico match.
Now we don't find that kind of excitement anymore and of course the fans of the team and the fans of the star players must really miss that condition and hope it can happen again. But it is very unreasonable to expect something that is impossible to happen again and just hope to have a new star player who can bring back that moment.
