I think that Barca vs Sevilla will not be a very interesting game... Barca plays very good home games and Sevilla, as you have already said, now plays very badly... I think the odds for Barca to win 1,4 are very good... With that you can try to make a multi bet...
With Sevilla's condition still not having a good performance, it is quite natural that this match is a little difficult but when looking at some of Sevilla's playing records in the past season, especially when getting a much better opponent, they actually always try to play better and this could be surprising.
Even with their current performance, Sevilla will definitely have difficulties but I think they will be quite capable of reducing the dominance of Barcelona.
Barcelona are definitely the favorites in this match especially they play at Camp Nou with full support of fans but there could be something good that Sevilla will show today.
Barcelona is still the favorite in every aspect, they can control the game better and I think this match will be less enjoyable if you see that some of the matches that Sevilla played didn't go well. The depth of the Sevilla and Barcelona squads now has a significant difference in that to block front line attacks, Xavi maximizes Lewandowski, and then utilizes Joao Felix and Joao Cancelo, who are increasingly being trusted to be the starting eleven.
Atletico Madrid played that very game with precision and determination to take all three points off the match from when the referee blowed his whistle for the kickoff of the match till the very last minute of the game and that I think were the major reasons they won their Spanish La Liga game against Osasuna.
After the victory over Osasuna and for this season Atletico Madrid is much more of a competitor to Barcelona than Real Madrid, and I think that can be reconsidered by anyone. Atletico Madrid will face Cadiz this week so that with 1 match they can move up to 4th in the standings.
