Everton climbed out of the Premier League relegation zone on Saturday with a well-deserved 2-0 victory against West Ham that eased the pressure on Marco Silva.
The Portuguese boss described the match at Goodison Park as a "must-win" game following four straight league defeats and a goal from Brazil forward Bernard in the 17th minute set his side on their way.
Everton dominated the match and had multiple chances to extend their lead but were forced to wait until injury time to score their second, through late substitute Gylfi Sigurdsson.
Victory in Saturday's early kick-off lifted Everton to the relative safety of 12th in the table, one place above struggling Manchester United, ahead of the later fixtures.
"It was a fantastic performance," Sigurdsson told BT Sport.
"We had a lot of chances, especially in the second half. You never know when it's 1-0 -- you always want to get more.
"They are dangerous going forward and their goalkeeper made some spectacular saves. I was pleased to come on and give us a bit of comfort. There was a real purpose to our game today."
