Pundits Gary Neville had marked the Swiss global down as "unprofessional" during the World Cup and questioned why Liverpool were even pursuing a deal for the 26-year-old, while brother Phil went one further and branded him a "disgrace" for his perceived lack of effort during Stoke City's relegation season.
"I hope I can repeat that because I know how it feels to win the Champions League", Shaqiri told Sky Sports.
'I've played in the Premier League for three years and know what it is about.
"We played, played, played, they got the ball and were away".
"The most important thing is to go to the last limit and to try to do the small things that will help us win titles".
"When I heard the club wanted me I wanted to come because I've known him [Klopp] a long time".
"I have seen many fans and they are really happy that I'm here".
Jurgen Klopp joins Mark Ogden to discuss his expectations for Liverpool's season, Mohamed Salah's fitness, his thoughts on Christian Pulisic and more.
Shaqiri could make his debut for Liverpool during Saturday's International Champions Cup clash with Manchester United. I'm looking forward to the new season and I hope we can finally win titles. I think everybody knows I was the best player.
"It's always hard, you always have competition everywhere in the world", he explained. I've played in Europe and have a lot of experience. Adam blamed the "so-called big players" for Stoke's relegation who "never turned up for us and never performed", aimed mostly at Shaqiri. "Everybody knows that a few years ago I wanted to come here but it didn't work out because Bayern blocked the move".
"It's totally wrong, I think", Shaqiri said of questions raised about his professionalism during his time at Stoke.
Shaqiri is focused only on becoming a success at Liverpool, four years after his hopes of joining the club were ruined by former club Bayern Munich. And you need every player to be successful in a long season.
But the Switzerland worldwide has hit back at the two brothers, claiming that they might be criticising him for joining up with the Reds, the biggest rival of Man United.
