He said: "I have had 4-4-2 in mind for a long time, I decided to play six players with an offensive mentality and when you play like that you need to keep the ball well at all times. It gave us more options in terms of movement and we created more problems."
"We will always try different possibilities but it depends on which players you have fit. If you don't have all the players available then it is difficult to use different formations but the more we have available, the more options we have," Benitez added.
The Reds boss also reiterated his confidence in the team, adding: "I think we will finish in the top four. We know it is a long race and we need to win more games. I'm delighted because coming from behind shows the right mentality and character. We had character, clear ideas and intensity during the game."
