Refereeing errors prevent the win, but so does a twenty minute performance

Arsenal 0 Sunderland 0
(Premiership)

I didn't catch the Leyton Orient game live and as such couldn't comment on it during the week, but it was reassuring to not see a hangover from the cup final defeat that preceded it. On many occasions in the past, one bad performance has rolled into another, and before you knew it, four matches had passed, and all hopes for trophies had disappeared in the blink of an eye.
