referee, injuries, under-par subs and fitness
these facts are killing Arsenal

it's understandable on 1st half when AW played a def tactic with high def-line. with 2-1 on hand, jz def n counter attack
they went to attack on 2nd half but RVP gt send off by a Joker-referee

shame on Barca and their fans, indeed.
when our player injured, they jz urged to get them off n play on
when their player injured, they take their time
this is absolutely no sportsmanship
u might wins all the trophies, but u might not wins all the respect
