The club's ownership throughout the month of January remains in question, with current owner Mike Ashley in advanced discussions about a £300m sale to Amanda Staveley's PCP Capital Partners.
"We knew this could be difficult," Benitez told Match of the Day after today's game. "Two or three games we could draw or win. We need to be competitive like today and keep going. We are a young team. When you're not winning you lose confidence.
"We have to keep working this way. Try to get a result. In January, try to bring in people. The fans know the team will be tough. They also know we need something in January - that will help the current squad."
Ashley has previously suggested that there will be minimal funds available for Benitez to strengthen in January should a takeover deal not go through.
