Everton stars were quick to call out the decision which cost them their first points of the Premier League season after James Tarkowski conceded a penalty in the 82nd minute against Leeds.
The Toffees defender was caught by a streaking effort from Anton Stach, blocking the ball out of danger with his arm as he fell to the turf.
Although Tarkowski believed that his arm was in a natural position, the handball was given, forcing Jordan Pickford to test his mettle between the sticks for the visitors.
After looking the livelier side in the contest, Leeds were able to provide the difference on the scoresheet as debutant Lukas Nmecha was nerveless from the spot to hand the hosts the 1-0 win.
