The club officially announced the transfer on Saturday afternoon, with the 23-year-old following defender Konstantinos Tsimikas and midfielder Thiago Alcantara through the door to become the Reds’ third signing of the summer.
He takes the vacant No.20 shirt, and spoke out at his delight at joining to the club’s official website.
“It’s just a really exciting moment for me and my family,” he said.
“All of my path since I was a kid and now, to join a club like Liverpool – the world champions – is just unbelievable. I just want to get started.
“It is one of the best teams in the world – the best at the moment because they are world champions. When you look at the Premier League, you always see Liverpool as one of the biggest teams in the country, so it’s impossible to say no.
“So we just want to come [here], to give our best and hopefully I can become a good option for Liverpool in the future.”
On whether the No.20 had any significance to him, he added: “No, not really. But I think it’s a good number and hopefully I can do good things with it.
“I think I am a team player. I play up front and my job is to find a way to score goals and to provide assists and that’s what they can expect from me – that I will always do my best. I will always try to help the team in the best way possible.
“They [the fans] can count on me because now I am one of them and I will give my best.”
