The in-form Bees dominated [the opening period](https://www.standard.co.uk/sport/football/chelsea-fc-vs-brentford-live-stream-latest-score-updates-result-premier-league-b1266871.html), going close on several occasions including through a Mathias Jensen that clipped the outside of the post, but it was the hosts who led at the break thanks to VAR ruling that Pedro was just about onside before rifling the ball into the roof of the net.
Brentford came flying out of the blocks after the interval, too, but were unable to capitalise on the chances they created before a defensive blunder allowed Liam Delap to win a penalty, which Palmer calmly converted.
That provided the Blues the cushion they needed to see out the final quarter of an hour plus stoppages and earn Rosenior has first three points at the helm in England’s top flight.
