Even though Barcelona's chance is near zero to reach the title, I think that they will still be the winner of the Celta game. They will want to maintain their place and maybe capture the second place. Because Sevilla also can get past them as there is only 2-point gap between them.
That is very shocking to see how see lost the grip over the game and lost it easily. I also was pretty sure about that it will be an easy victory for them but they failed to take advantage and surprisingly Celta Vigo made that possible to get points against them.
