Benitez said: "If I need to make gambles, then I will make gambles.
"We have been in two Champions League finals and an FA Cup final. That is because we change the side. Sometimes it is good and works, sometimes not. But nobody really knows whether what I do is right. All I will say is that Liverpool and me have won a lot of trophies doing this.
"Sometimes maybe I take too many gambles. But it is necessary sometimes when opponents have top class, expensive players, and lots of them. If they have five players who cost £20m and we have just one, you need to use that player in the right moment. If you don't win, people blame you.
He added: "We played against Havant and people said, 'play your best team.' But you cannot do that against a team like that, if people want that it is because they do not know what it takes to win trophies and trophies and trophies.
"If you cannot do things like that against smaller teams then you will just not be able to compete all the time against Premier League teams. You must change things for games like that."
The Spanish boss says: "People say I gamble too much with rotation and changes. But the answer to that is to look at Torres, he has played a lot of games for us recently and then he has another game with Spain, and he gets injured. He is continuing to play at a high level all the time. Players must rest also.
"We have half a dozen players in this situation, they all need to be changed and to rest. But everyone keeps talking about me playing my strongest team, and then you see what happens. I do not like to say what is my strongest team, I must use all the players with the demands we have. If you pick the same team all the time you will find at the end of the season that you cannot win trophies."
