The Germany international, who has impressed for his country during the international break, is expected to be in the starting line-up for Saturday's big home clash with rivals Manchester United.
Can admits the Reds' defence, which has shipped 12 Premier League goals already, has been at fault but is also aware their attacking players have failed to take their chances in games.
He told Sport Bild: "It’s definitely a fact that we have recently defended badly and conceded too many goals. But I still believe that when we scored goals, we won the games. Then nobody was speaking about the defence.
"The coach himself says we didn’t play badly. We almost dominated the opponents in all games and were the better team."
Can, who is out of contract at the end of the season and has been heavily linked with a move to Juventus, says with more luck Liverpool would have picked up more points but has backed boss Jurgen Klopp to turn things around.
He added: "Jurgen Klopp is convinced that only the necessary luck is missing to return to winning. At Liverpool, however, nobody questions the coach. Jurgen Klopp is a top, top trainer."
