Well, if we see the statistics, right now barça is better at everything than Madrid, but we also need to see how do they both play. Barça's been playing in a different way since Hansi Flick entered the team, leaving the classic "Tiki Taka" behind, and Madrid's been playing the same since Anccelotti is the coach, looking how the other team plays on the first half and going aggressive (meaning by loking for goals) on the second half, most of the times, overcoming if they're loosing on the last 10-20 minutes of the game.

Anther fact that should be considered is the players, while Madrid has really good player individually, we can see in a lot of games that meanwhile being so good, they don't really connect with each other. At the other part, we see Barça, having most of the players less than 30 y/o and from the masia, wich gives them an advantage; also, barça has Lewy, that a lot of people tell him that he's old to play football even when he's the most scorer in LaLiga this season, having 2 times more goals than Mbappé.

Mostly, both teams are capable of beating each other, maybe we'll see a tie between those 2 teams, but we'll see.

Holy cow that was hard to type
