Crystal Palace's 19-game unbeaten run was ended by Jack Grealish's late winner for Everton on Sunday.
Palace missed the chance to go second as they suffered a European hangover in a 2-1 loss at the Hill Dickinson Stadium.
The Eagles were dominant in the first 45 minutes but were left to rue not adding to Daniel Munoz's finish from Ismaila Sarr's pass.
However, their Conference League exertions in winning away to Dynamo Kyiv on Thursday took their toll in the second half.
Iliman Ndiaye equalised from the penalty spot after Maxence Lacroix clumsily upended Beto as Everton fought back to avoid a first defeat at their new home.
Grealish then got fortunate for his first Everton goal as Munoz's attempted clearance rebounded off the Manchester City loanee into the roof of the net.
