I didn't like lucho at all but he managed to do some great things.
1)His rotation helped our players stay healthy and fit.
2)Rightly let suarez play in the middle. Ok, messi thought of this but lucho accepted it and made it work.
3)I don't know how but he inspired our players and made them fighters. Do you remember how tame and nerveless barca was last season under tata? Now we fought like lions, especially in the first half of the season that we didn't play as good and many games turned into fights, when someone scored on us we would immediately score back. That shows great attitude and spirit.
4)He also found the right position and way to play for rocketic, lucho helped him blend in our first team.
5)His rotation with keepers worked out, instead of having 1 keeper sulking and not playing to his best, lucho managed to have both in top shape.
Grande lucho, I hope he stays.
