This will have to go down as one of the greatest Chelsea performances during Emma Hayes’ tenure.
One for the ages, one for the history books - and possibly one that helps them reach the Champions League final at the expense of the holders.
Barcelona had not lost at home since February 13, 2019. They had not lost all season. Their record in the Spanish league stands at 96 goals scored and just six conceded.
Chelsea needed a perfect performance to have a chance. Hayes’ players gave her that and more.
