The Dane had a huge impact at both ends of the pitch, putting in a superb defensive display as well as scoring the equaliser for his side.
His clever venture forward resulted in the ball falling between himself and the on-rushing goalkeeper Mark Flekken, with Andersen's instinctive sliding challenge seeing him reach the ball first and poke past the Bees 'keeper into the open net.
Andersen's performance earned him a player rating of 9.3 - the highest of any in the Premier League over the weekend and the second highest across the whole season so far.
He performed his defensive duties when required, making seven clearances and three tackles, as well as completing four key passes.
His form at the start of the season has been fantastic and Palace fans will be hoping it can continue for the rest of the campaign.
