Marcus Rashford, signed on loan from Manchester United in the January transfer window, recorded two assists for fellow new loanee Marco Asensio as Villa came from behind to inflict a third straight defeat on the Blues.
Chelsea raced into an early lead at Villa Park when Enzo Fernandez turned home Pedro Neto’s cross, but a half-time substitution from Unai Emery proved to be the difference.
Took full advantage of extra licence to attack by crashing the six-yard box to open scoring, but slow out to play Rashford onside for Villa leveller.
Looked to have made another massive one from Malen late on, but clanger from resulting corner gifted Villa all three points.
Moved back to last season’s role off the right as part of rejig and looked more threatening but scoring touch has deserted him.
