This is a new debut for Jude Bellingham in Madrid, because it is still in a friendly match coach Carlo Ancelotti trying to find the right position for him, Ancelotti has made several game options throughout pre-season to find the maximum performance from all players. However, this defeat will see Ancelotti return to make more correcting in his first team before LaLiga starts
If you see potential that is quite right for Bellingham's position, it is an attacking midfielder who is believed to be a player who will fill Luka Modric place next season. Yes, ancelotti tried several formation changes in order to find the ideal position for their new players but in the last two matches they suffered defeats which resulted in the testing of the new formation failing to reap success. And most likely 4-3-3 is the ideal formation that has integrated with player Real Madrid.
The defeat in the last two matches has indeed made Real Madrid look like it wasn't quite ready to start an official match when La Liga started. Ancelotti still has time to find the best strategy to use this season. But my assessment is that they need a goalscorer who is more successful like Mbappe.
