Liverpool fell to a sixth Premier League loss on Saturday afternoon as they were defeated 3-0 by Nottingham Forest at Anfield.
The visitors took the lead when Murillo produced an excellent touch and finish from Elliot Anderson's corner, with the officials deeming that Alisson's view wasn't restricted by the position of Dan Ndoye.
Forest striker Igor Jesus had the ball in the net moments later before it was disallowed for a handball, in what was the first of the home side's struggles to reclaim control of the game.
