It sounds like what you're saying is quite realistic, but Barcelona also want to be in the best position at the end of the season. And the best position is in second place, because speaking for the champion is very difficult, if not impossible. Yes the current position is indeed much better than at the beginning of the season when they were outside of the top 4. But I believe that they will still finish second.
2nd place is still safe for Barcelona I'm just predicting the next Barcelona match it will depend on the Sevilla match
If Sevilla lose or draw maybe Barcelona will do it too Barcelona just trying to stay above Sevilla in this case in the 2nd place
This is the classic mode in every match at the end of the season I mean if the match had no impact on the standings.
