Gary Neville has questioned Everton's mentality after Marco Silva's side lost 2-0 to Aston Villa on Friday night.
Goals from Wesley and Anwar El Ghazi condemned the Toffees to their first defeat of the season and saw them miss out on the chance to move top of the Premier League.
And Sky Sports pundit Neville believes that the defeat was a reminder of Everton's problems from last season.
He said: "There was a little bit of subtlety lacking. Is it a mentality thing? A bit of quality? I think he'll be so frustrated, Marco Silva, with that, because that was a reminder of last season. He won't want to go through that again.
"That was a big chance, the second half, for Everton to put prove they've put last season behind them and they've progressed, but it sets them back a little bit."

Everton missed a number of chances throughout the game, with debutant Alex Iwobi hitting the post and Dominic Calvert-Lewin and Theo Walcott both guilty of big misses.
Neville and fellow pundit Jamie Carragher discussed Everton's goalscoring problems at length after the game - and both men lamented the Toffees' profligate finishing.
Neville said: "They should have taken their chances. I think they had good moments in the game, but then you've got to be ruthless. They just lack that ruthlessness and that's a problem they're going to have to get over.
"It chased them all through last season, and I don't know how you teach mentality to people to score goals. But on the pitch they've just got to go and believe more, that belief and mentality is just not quite there."
Asked what was wrong with Everton's attack, Carragher added: "One, maybe quality. But also I don't think the Everton players believe they're going to score.
"Round the edge of the box so often, they were just passing it to each other. Too often they were passing responsibility. No one's really got that personality or character to go and make something happen.
"It felt like the whole game was just waiting for (Moise) Kean to come off the bench, because Evertonians have been crying out for a centre-forward since Romelu Lukaku left."
