Liverpool goalkeeper Loris Karius has said that it was a simple decision to join the club when Jurgen Klopp came calling during the summer.

The 23-year-old moved to Anfield from Mainz after making almost 100 Bundesliga appearances, and he has quickly displaced Simon Mignolet as the team's number one.

The Reds have made an encouraging start to the season and currently sit top of the Premier League table after 11 games, and Karius was always confident of Klopp's ability to transform the team.

"When I heard Klopp wanted me, I was really excited because it felt like a huge reward after everything I'd been through, and also because I know how hard the manager works for success. I was watching Liverpool already, like many people in Germany, who wanted to follow what he was doing in the Premier League," he told Goal.com.

"You could already see last season the way of playing at the club changed and even though the results now and then weren't always as good as what people wanted, you could notice what he was building and that the team was stronger.

"I knew that in the summer, with the time he had to create his team with transfers and pre-season, that he would really transform Liverpool. I believed in everything he told me. I had a really good talk with him, and it was not a hard decision to make."

Liverpool's next match sees them face Southampton at St Mary's after the international break.
