The Reds may have tied up the signings of Javier Manquillo, Dejan Lovren, Emre Can, Adam Lallana, Lazar Markovic and Rickie Lambert this summer, but the longest running saga of them all was over Sevilla left back Alberto Moreno, who was clearly identified as a top transfer target by manager Brendan Rodgers.
A number of times, the deal looked set for completion - yet, every time, the deal fell through for one reason or another. Liverpool even loaned striker Iago Aspas to Sevilla as a sweetener for a deal, but Moreno's arrival was only confirmed last week as the 22-year-old joined in a £12m deal.
The full back was seen crying after saying goodbye to his Sevilla team mates after their European Super Cup final match against Real Madrid last week - after all, Moreno was born in Seville and came through the ranks with Unai Emery's side, and didn't deny how upset he was to be leaving his boyhood club.
Now, Moreno has already hinted at a potential return to Sevilla one day, but given that Liverpool strongy believe that he is their left back of the future, that may be some time away.
"I want to offer my thanks to everyone at the club. The president, the board of directors and all the managers I’ve worked with, through the youth system and especially, I want to thank Unai Emery, who gave me the opportunity to be with the first-team and for always showing confidence in me."
"I also say farewell to the great fans of this club. I have always been comfortable with them and they have treated me superbly. It’s always painful leaving the club where I’ve always been and I hope to return one day."
"I arrived here in 2004. Sevilla is the club which has given me everything, helping me grow as a player and a person. This isn’t a goodbye, but rather a farewell. I hope to be back here one day."
"I never imagined it would be as painful as this, but it’s true that when you start to say goodbye to your team-mates and all the people around the club, it hurts, but I leave to keep growing as a player."
This is nothing to worry about for Liverpool fans - Moreno is naturally committed to the Reds and is excited to get started at Anfield, and the fact that he left a club so close to his heart in order to move to Anfield is actually a sign of how excited he is to develop under Rodgers.
Will Moreno solve Liverpool's left back problems?
