Maybe Sevilla can beat Real Madrid if they succeed in pressing and continuously attacking. But attacking continuously is not a good option and Real Madrid with its counter attack could destroy Sevilla within 90 minutes. The safe bet is of course on Real Madrid and I would bet on Real Madrid without the slightest doubt.
Maybe many people will not hesitate to bet on Real Madrid because in general Sevilla is not a fairly equal opponent to Real Madrid so Sevilla may have to accept the bitter reality of being defeated by Real Madrid at home. And I am very sure that Real Madrid will make it difficult for Sevilla first by continuing to build attacks from the start so that no goals are conceded into the net.
Well Sevilla would be playing with a home advantage but I don't think they'll be able to take the 3 points if there's a worst case scenario for Realmadrid the game could end in a draw but I doubt if Madrid would lose that game, they got better players from defense to attack and are currently the best performing team in Laliga currently and that's why they're at the 1st place in the table, however Sevilla have been underperforming since the beginning of this season and are not in the top 10 in the standings currently.
Realmadrid are the favorites to win the game and Sevilla defense would not be able to stand against Vinicius Junior who's been in a good form since he returned from injury and his partnership with Jude Bellingham on the pitch is Amazing,and they not only dominate the game mostly but put up a very good display against Sevilla in their home ground, Sevilla should just do their best and accept their fate, they might be lucky to get a draw.
