The 2-1 win over Everton moved Chelsea back to third place and ensured they face bottom club QPR today at Stamford Bridge looking for a seventh win in eight games.
“We have to keep believing,” said the midfielder.
Chelsea skipper John Terry is not expected to recover from a knee injury while goalkeeper Petr Cech is also a doubt.
Meanwhile, QPR’s home defeat to Liverpool left Harry Redknapp’s side eight points adrift of safety although Benitez has cautioned against underestimating Chelsea’s near neighbours.
