Marco Silva insists his Everton side must be more ruthless in front of goal after they were beaten 3-1 by West Ham United on Sunday despite carving out a host of chances.
The Blues were a threat throughout at Goodison Park but Gylfi Sigurdsson’s thumping header on the stroke of half-time was all they had to show for their efforts.
Andriy Yarmolenko had earlier struck twice to put the Hammers 2-0 ahead and – while skipper Sigurdsson’s pinpoint finish from Jonjoe Kenny’s cross halved the deficit – Marko Arnautovic struck in the second half for West Ham’s third.
While boss Silva admitted his side were not at their best - and rued errors that led to the visitors' goals - he is convinced the Blues could have come away with a better result had they been more clinical in front of goal.
“Before they scored, we started the match well, with good intensity,” he said. “Their goal changed the game and we lost some confidence, but even then we had chances to make it 1-1.
“Before half-time, I changed the formation, and we scored to make it 2-1. And even in the second half - without a good performance and playing more with the heart than the mind in some moments – we created enough chances to make it a different result.
“They created three or four chances in the game and scored three goals. and we created maybe four or five clear chances and scored just one.
“We have to be more aggressive in our offensive third and score in the right moments.”
Silva added the players are still acclimatising to his ideas and methods and insisted they will be working tirelessly on the training pitch ahead of next Sunday’s game at Arsenal.
He is confident his side will learn from the West Ham defeat and turn in an improved display at the Emirates Stadium.
“There are many things we have to improve but, even if we achieved a good result, I’d tell you the same.
“Of course, when the result isn’t the best, we have to improve more. It is a big lesson for us, what happened this afternoon. I have already told our players this, as well.
“But we will learn from our mistakes and take positives, too. We are in the beginning of the process and we are working every day to improve.”
