It just happens for Mbappe to be able to win an important trophy since the first official game he will play for Real Madrid.I think he will be a lucky player to achieve such feat and I think Real Madrid is more than capable to beat a team like Atalanta which is playing for the first time in their history at such levels.I am confident Real will win the Super Cup as I remember them being down by Napoli a much stronger team than Atalanta and they changed things around within 16 minutes left to play,so based on this I doubt they will have any problems against Atalanta.
Mbappe joined Real Madrid at the perfect time. If Real Madrid beats Atalanta in the Super Cup, Mbappe will start to enjoy European glory in his first season at Real Madrid. Even though Atalanta beat Bayern Leverkusen in the Europa League finals, they are not a threat to Real Madrid. Real Madrid players will play at their best level just to win the Super Cup for Mbappe so that he will know that he is in a club that always wins the prestigious trophy. Mbappe will also want to start scoring for Real Madrid in the Super Cup against Atalanta to win his first European glory and also start gaining his place at Real Madrid. I think Atalanta has no chance of beating Real Madrid in the Super Cup.
