Against Geta i even think they can go for a 4-0 win. At home Barca is at is' best.
You seem to have forgotten that they have champions league as well so instead of wasting their stamina for such game, enrique will make a wise choice by not playing most of his player and let them have some rest. Not to mention that there are risk that they might get injuries while playing
I agree with you, that enrique better to save some important players. because they will get a pretty strong opponent in the quarterfinals. and now I think barcelona is safe enough. and I think some important players will not play full.
