Mignolet played 90 Barclays Premier League matches during his time with former club Sunderland, keeping 30 clean sheets along the way, but senses a different kind of ambition at his new team.
He told liverpoolfc.com: "For me it's a big step forward and I'm very pleased to be training with the team for two weeks now. I spoke to the manager and he told me that it's going to be a big step forward.
"We play the first game on Saturday and after that, with the more we do on tour, I'll see how big a step forward it is for me. At the moment, it's only training and I have to get used to the players and the way of playing. Once we get going I'll know what it's going to be like.
"When I came in for the first couple of training sessions, I saw that everybody is very hungry and ambitious to get going, everybody wants to take a step forward and push on into the top four.
"There's big ambition around the club. I also noticed that from the conversations I had with the goalkeeping coach and the gaffer. I saw that they are very ambitious, want to get forward, winning trophies and getting into the top four."
