#4 Alberto Moreno (Liverpool)

Much like Christensen, Alberto Moreno has also been invisible from the Liverpool team for ages. Andrew Robertson's top-notch performances are one reason but still, he hasn't even been playing as much as Riqui Puig has played at Barcelona. He is not even considered a squad-player at the moment.
For a player who was once welcomed at the club from Seville, who the Kopites thought might be a great fit in their attacking branded football, this seems really unfair. He is a player like Trent Alexander-Arnold, less of a defensive player and a huge attacking threat. It is really unfortunate that Klopp and Rodgers, both failed to identify his weakness, which indeed cost them a Europa League title, notably.
However, he is still a player who could be a great squad player or even a starter at certain places. The recent interest from Catalonia is a huge one and considering their more attacking playing style, Moreno would be a good squad player and backup for Alba.
But surely he is not going to be his long-term replacement. Even the Red Devils are in need of a backup left back. The best-suited place could be Lyon because he can find a starting place as Ferland Mendy is attracting a lot of attention from big clubs.
Possible destinations: Lyon, Manchester United, Barcelona
