Everton enjoyed an emphatic 3-0 win over Fulham on Saturday.
Gylfi Sigurdsson atoned for an earlier penalty miss with a second-half double.
The Iceland playmaker had blasted a 52nd-minute spot-kick against the bar but four minutes later he drilled home the opener from the edge of the box then grabbed his second late on after substitute Cenk Tosun had sealed the points for the hosts.
Everton boss Marco Silva was happy with the clean sheet: "It is one of the most important things this afternoon.
"The three points is the most important for us but with a clean sheet, it is something we have been working to achieve, and it will grow our confidence as a team."
On Sigurdsson, who missed a penalty with the scores at 0-0, but reacted by breaking the deadlock soon after, Silva added: "Fantastic character and personality is important. Our team showed that character as well.
"He missed the penalty but after one or two minutes he began working in his way.
"The football this afternoon was fair with him after he missed the penalty. He works hard everyday."
