Barcelona team is much stronger than Sevilla at the moment. The performance of the Sevilla team is now very poor. But let's not forget that this team is very experienced. They won the Europa League last season. And so if Barcelona make any mistakes in this match, they are likely to lose points. Barcelona are favorites in this match but they have to perform very carefully. Sevilla usually play defensive tactics. And so Barcelona should adopt an attacking strategy in this match. Barcelona dropped points against Mallorca in the last match. And so if Barcelona wants to stay in the title fight, they have to get full points in this match. If not, the team will fall further behind Real Madrid.
I tend to agree with you considering Barcelona is the home team today. The squad depth of the two teams is very different, the performance of the two teams is also different. I think Xavi is experienced enough to face Sevilla's resistance even though Barcelona lost important points in the match against Mallorca. Sevilla won with a big score against Almeria in the previous match, but this is not the only reason why Barcelona should be wary of Sevilla.
I just hope that Xavi and his players don't underestimate Sevilla in this match. Barcelona must perform optimally to win 3 home points and this will take them to the top while waiting for the results of the Girona vs Real Madrid match tomorrow. I'm sure Barcelona can win their home game today, but I know it will be difficult.
