Everton manager Frank Lampard has said his side must have "better quality" to escape Premier League relegation but remained optimistic about survival.
"We're in this position and know the reality but we have 10 games and a lot of points to fight for," said Lampard.
"If we keep on the path we showed I have a strong belief we will be OK."
"We have to show more quality - and there is that in this group - to stay up," added Lampard after his side lost for the sixth time in eight league matches since he replaced the sacked Rafael Benitez in January.
"Everton has a huge history and a fanbase. At the moment we're working to get through this moment. Myself and the players are giving everything. The fans can know if we keep doing that over 10 games we will be OK."
The Toffees, who are 17th in the standings, fell 2-1 at West Ham and are only three points above the relegation zone heading into Wednesday's away match against 19th-placed Burnley.
