Barcelona is not doing absolutely bad this season especially in La Liga they are doing good and winning good number of matches they are also playing good football to the pleasant of the eyes. But their major challenge was in the Champions League, I didn't understand the spirit in which they approach to the Champions League it really affected them.
They most likely have seen more challenge in the champions league than they have seen in the La Liga. I watched their last La Liga game and saw how they were having a great time attacking the opposition's defense and scoring goals, it was not the same in their last Champions League game. I feel that the team is intimidating to some other teams in the La Liga who become too intimidated to even try to score them. In the champions league, it is a different mentality, most teams are not intimidated by them, they try to score them and see that it is not as difficult as they look. If teams in the La Liga try to score anytime they play Barcelona instead of planning to defend only, they will discover that they are just like any other team and Barcelona could begin to have problems winning games because their defense is not as thorough as their attackers are.
The pressure for the Champions League is at least over and for now Barcelona will only focus on La Liga and also, of course Barcelona will be better off in the Europa League too. Last season Barcelona fell in the quarter-finals of the Europa League and who would have thought, Barcelona last season was eliminated by Eintracht Frankfurt in the Europa League which even Eintracht Frankfurt was not the strongest team in the Bundesliga.
This season, after Barcelona failed to finish as group runners-up in the Champions League and Barcelona will return to the Europa League, Barcelona basically has the qualities to be the winner of the Europa League title this season.
It will be interesting to see whether Barcelona are still unlucky to win the Europa League title, because we know that Xavi still can't make Barcelona better even though they already have a luxurious squad.
In matchday 12 Barcelona will play away against Valencia, with Barcelona already eliminated from the Champions League, Barcelona should be able to beat Valencia on matchday 12. Although indeed, Valencia is also not a weak team at all, but so far even though Valencia is in 9th place with 15 points, Valencia is still not consistent enough.
Also, from the last five matches of Valencia they only got one win, three draws and even yesterday Valencia lost at home by Mallorca. With such a bad record, Barcelona should be able to beat Valencia with a big score, considering that Barcelona has a player who is currently the top scorer then of course Barcelona will succeed to beat Valencia at least with a gap of two goals or more.
