Luis Enrique is the best barsa manager in the club's history counting first 2 seasons, no other manager comes even close, not even Guardiola, but many (new) fans are conditioned to Guardiola's barsa and romatisism regarding tiki taka.
1 champions league winning treble and 1 domestic double in first 2 seasons has not been achieved by any other football manager in the history of football, only Mourinho is comparable with one UEFA cup winning treble and 1 ChL double with Porto. Luis Enrique's team has scored more goals than ANY other team in the HISTORY of Football when counting first two seasons. Luis Enrique's team is the first in Champions League history to eliminate the defending league champions of England, Germany, Italy and France.
