In this round of Barcelona will go on with the hosting team Elche, which is a little out of the relegation zone but since the last placed teams share only 3 points, on the other side of Barcelona has a point less than Real Madrid, which has a game in hand.
Barca recently played against Elche in the Cup and won a total score of 9:0. The first match at the Camp Nou finished 5:0 and there Barcelona play with strong line up. In the second match was played in a totally altered Barca team that played reservists and there Elche could not do anything, slowly they lost 0:4. Barca lags behind Real Madrid 1 point and has a game more, and is not entitled to slip up and go into every game with the strongest lineup. Messi, Neymar and Suarez is killing this season, the defense is solid and I doubt that there can be dropped points.
On the other hand Elche 16 on the table and only three points separating them from last position and will try bunker to do something, but that they failed the last two times and I believe it will not last in this section so you will probably need to another match to seek points.
Barcelona is a series of five victories where they received only one hit and scored 17. I do not believe that Elche able to stop Barcelona so I expect a routine victory with minimum 2 goals difference.
