"I know we didn't play well against Arsenal. That's clear and I accept that. We were a bit better in the second half, but we know the kind of football we want to see," said Benitez.
"We want to see players getting into wide areas, putting in lots of crosses and playing well. There were times on Sunday we played really bad.
"I've said to the players they now need to show their character. We showed some in the second half the other day, and now we need to do the same in the next games. We have nine Premiership games and the FA Cup.
"To change things, you must show the people on the pitch. It's no good talking, you must play well, score goals and win."
