Barcelona has difficulties scoring goals, while Real Madrid scored 5 goals against Atletico.
I know that some of the goals scored by Real were a little bit lucky, but that doesn't mean that the attacking players of Real are weak.
Real Madrid is the clear favorite for winning the Supercup of Spain. They will become even stronger, when Mbappe joins the squad in the summer. Barcelona probably needs a new coach and several new players. Xavi can't find a way to make the team score more goals.
Real Madrid team scored 5 goals against Atletico Madrid. And in this match Vinicius performed well. However, Real Madrid won the match 5-3. However, Vini's performance is quite erratic. It is unlikely that we will see a better performance from Vini in every match. This team is still dependent on their midfield. Real Madrid are favorites for the Super Cup title. But there is no chance to underestimate the Barcelona team. Despite not winning by a big margin against Osasuna, Barcelona's performance was good enough. However, the team still relies on Lewandowski to score. If they do not reduce this dependence, it will not be possible for Barcelona to maintain the continuity of good performance.
