But his departure from the Midlands club has now been confirmed.
The player told Liverpool’s official website: “It’s just a really exciting moment for me and my family. 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.”
The announcement of Jota came a day after Liverpool confirmed the signing of Thiago Alcantara from Bayern Munich.
Thiago, 29, has signed a four-year deal after a £25m fee was agreed between the two clubs earlier this week.
Klopp refused to rule out any further incomings at his pre-match press conference ahead of Sunday’s visit to Chelsea and the arrival of Jota proves he was right not to do so.
