Theo Walcott’s 58th minute effort gave the Gunners some hope but Chelsea were able to hold out for a much-needed home win following two defeats and a draw at the venue in their past three outings.
"Happy... Because I think we were creating a lot of chances at home in the last few games, but not winning,” was Benitez’s response after the match.
"We were controlling the games and doing well.
"But today we had a lot of chances in the first half, were on top of them, controlling the game.
"Even in the second half, we had situations on the counter-attack where we could have scored another."
