Benitez has only been at Anfield three months but there has already been three international breaks in that time which have denied the boss valuable training time with the players, much to Benitez' consternation.
"Arsenal and Manchester United have had time to put their squad together," said Benitez.
"People have said to me 'You're in the same position as Chelsea, because they have a new manager and new players'. But I say 'no' to this. They have put together an expensive team with some players the manager knew very well from Portugal.
"Carvalho and Ferreira played for the manager at Porto and when I spoke to him he told me how important they will be because they understand the way he works.
"We lost our last two away games in the league, but we know Manchester United and Chelsea are very good teams with top players. They are at a high level. I'm sure we will get better results against other teams. Now, we need to get the confidence which comes from results.
"In the ten weeks since the start of the season we've had a lot of international breaks which haven't helped us.
"I don't know if we have suffered more than all the other teams because of the international break, but this week, on one day I trained with just five first team players.
"When you have a new manager there are a lot of new things to learn but we haven't had a lot of time to train.
"Now is a time for my players to understand what I want and practice. I can't just tell them to do things the way I want without giving them time to train.
"We've also lost players like Smicer and Nunez who would have helped the balance of the squad, then we lost Steven Gerrard. When you arrive with a new team and you need time, it doesn't help to have these problems.
"I'm sure this team will improve and we will win many games this season.
"If we can put together a few wins, we'll go up the table. We also have a game more to play than the rest. If we had three points more, you'd see where we are in the table and I know the supporters would feel happier."
