Marco Silva has admitted errors in his first defeat as Everton’s manager after West-Ham ran away 3-1 winners at Goodison Park.
A brace from Yarmolenko and a goal from Arnautovic condemned the Toffees to their first defeat of the campaign.
However, Marco Silva quickly pointed to mistakes from his players and poor finishing as the reasons for Everton’s defeat.
“We weren’t good enough to win the match, this is clear to me,” he said. “Our first 10 minutes was good, but the first mistake we made – we prepare for our opponent winning the ball and go straight to Arnautovic.
“And at this moment we did not do what we needed to do. We prepared for it, but we made too many mistakes.
“We reacted, but there was a second mistake. We changed the formation and scored to make it 2-1 and got back into the game. But even before we had two clear chances with just the goalkeeper.
“In the second half we developed clear chances – they had three and scored three, we had four or five and scored just one.
“Even without a good performance and some mistakes as well at this level, which you cannot take, I still think we had the clear chance to take a different result.”
“We have to improve every day to see what we did in the wrong way to improve our squad and improve for the next match.”
