In that match, Sevilla will definitely have difficulty getting full points because Barcelona will not embarrass themselves when the match takes place at their home base. Currently, Barcelona is a much better team than Sevilla who this season have experienced three defeats, three draws and three wins from the nine matches they have played. So I don't think Barcelona will have difficulty in that match because Barcelona will definitely try to continue to strengthen themselves at the top of the standings by getting full points in every match.
The statistics that you just gave about Sevilla has shown that the team is not that poor this seaosn and that results have also shown that they’re on an average level this season, so Barcelona should be careful of them because they can still turn the game around and win the match even if Barcelona is the better team to win the match with the statistics so far from each team this season. Barcelona will definitely try to win the match because they want to maintain that top of the standings and only with consistency can they make that happen, so they should show some of that in this match and win.
Even if a team is weak, it shouldn’t be underrated, as you said, but in this case Barcelona are doing well, and there is a way in which a team will be performing, and you will be giving them some assurance of winning some of their opponents. And that is what is happening with Real Madrid; their fans are always giving them a chance of winning their matches because they are doing well; if not for now that some of their players are injured, fans are always trusting them. In this case, Barcelona are doing well, and they will be playing at home, so I’m giving them a high chance of winning the game.
Real Madrid is just one great team that plays on a very big different level than any other team in the La Liga. I am very sure that even with their injury crisis, they have that very much confidence that they will be able to win the match easily. The match is very important for both teams though but some level of confidence and trust in yourself as a team can build more courage to prevail in the match and that’s what I feel Real Madrid are going to do when they play in the El-Classico against Barcelona.
