With takeover talks at the club continuing, Benitez was asked how he will guide Newcastle out of their recent rut, to which he told Sky Sports: "We will keep working harder and improve little things that have to change".
"We are a team that came from the Championship and where we are now could be expected". We have to talk.
"Our situation is that we did so well for a while (early in the season) that everybody was expecting that we could be in the top ten, but we knew that this team, coming back from the Championship previous year and doing the things that we did (ED: and didn't do...) in the summer, had to be near the bottom of the table".
"We have quite a lot (of names), but that's normal, because sometimes the clubs don't want to sell or they don't want to come".
The Magpies' poor record against Arsenal has continued, they have now lost their last ten consecutive Premier League games against the Gunners and have conceded 23 goals in that time. It dropped Rafa Benitez's side into the relegation zone with 15 points from 18 matches.
"It's frustrating [not to get anything from the game]", he added.
Benitez, speaking ahead of this afternoon's game against Arsenal at the Emirates Stadium, will also look closely at the loan market. "West Ham's the next game, and we've got to focus fully on that and make sure we do all we can to go there and get a good result".
"We had our chances (against Arsenal)".
"We are learning, it's a learning process we must do quickly if we are to get results now, but it's a long, long season".
"Two or three wins can turn the table around really quickly but we need to make sure that we show the same commitment and passion that we showed (against Arsenal) and be a bit more ruthless in front of goal".
