Sevilla are slowly finding their way back and have been pretty consistent so far. I ignore their few defeats in the last few matches, but this team is much stronger compared to the start of the season. The great thing about Sevilla is that they have been stronger since beating Manchester United in the Europa League quarter-final second leg. Sevilla are more motivated and they have good confidence to qualify for the final.
About the success of Barcelona, I honestly can't hide my joy. I've been very optimistic about Barcelona since the start of the season even though some people seem to insult them for no apparent reason. The best proof is the two titles that Barcelona managed to secure this season and they managed to beat their arch-rivals with a high difference in points.
Sevilla's big motivation is now to win the Europa League because they are only one step away from the final, in La Liga it is not so consistent if you look at Sevilla's appearance from the start of the season to the middle. But they have developed much more in the previous few matches and a total of eight matches have only lost one against Girona, now Sevilla's chance to qualify for the Champions League is only by winning the Europa League.
I'm not a Barcelona fan but I respect them, even though at the beginning of the season they had financial problems for the club and many people doubted their consistency, but Xavi proved it with the two titles they won this season. For La Liga we have to admit Barcelona's greatness but not in the Champions League and Europa League.
