Chelsea interim manager Rafael Benitez has admitted that he is "not 100%" sure of his job at Stamford Bridge.

The Blues were shocked by a 3-1 defeat to West Ham United at Upton Park in Saturday's early kickoff.

The result leaves the Spaniard still searching for his first win since he was given the Chelsea job.

Asked if he fears for his job, Benitez said: "No, I am not 100%.

"We didn't win today - that is the main thing.

"It could be in terms of, it's a top side, it's in the middle of the season and obviously the results were not the best, so we will try improve things and it will take some times maybe. We will see."

Benitez replaced Roberto Di Matteo, who was sacked following Chelsea's poor form in the Champions League.
