The Reds endured a difficult start to the season under new manager Brendan Rodgers, picking up just one victory in their opening six Premier League games.
However, Liverpool are currently unbeaten in seven games, propelling the Merseyside outfit up to 11th position, eight points behind fourth-placed West Bromwich Albion.
And Skrtel is confident that qualification for next season’s Champions League is an achievable goal if Rodgers’ side can continue their run.
“We have gone seven games in a row unbeaten and we’ll try to carry on this way,” Skrtel told Liverpool’s website.
“I think top four is a realistic aim because in our last few games we have turned in great performances and got good results. We have to carry on in this way and if we do, we can get what we want.
“The start of the season wasn’t the best for us but things are getting better and there’s not such a gap between where we are now and where we want to be at the end of the season.
“The start of the season wasn’t the best for me either. I made mistakes but I have learned from that. And in each game, I try to do my best and try to play the best I can.
“At the beginning of the season, the new manager came in and changed a few things. He changed the way we played and we knew that needed time.
“We needed to learn new tactics and ideas. We have worked together for four months now and I think things are starting to work for us.”
