But the Spaniard has admitted that rivals Manchester United are now in control of the Premier League title race.
“I am very disappointed because we have conceded four goals we wouldn’t normally concede,” said Benitez.
“We made massive mistakes. You don’t remember any saves from Pepe Reina. It’s just four chances and four goals – all of them from our mistakes.
“You never know what can happen in football, so we have to be confident we’ll have chances until the end of the season.
“United are in the driving seat, but we will see what happens on Wednesday. If they win it will be more difficult, but they have to win. They also have to play Arsenal, so we will see.
“I have explained before that, one Saturday when I was with Tenerife, we drew 1-1 at home and were fourth. Seville and Betis were first and second but they lost the next day, so we had one more point.
“The positive thing is that we’ve scored four goals against Arsenal in a very good game for the supporters. The other positive thing was the team fighting right until the end. To score another goal at the end shows this team has very good character.”
