#1 Steven Bergwijn (PSV)

Steven Bergwijn is a 21-year-old left winger who currently plays for PSV in the Eredivisie. He also represents the Netherlands national team, having made three appearances since his debut in October 2018.
Bergwijn has been steadily improving in recent years to the point where now, he's starting virtually every game for the Dutch side. In just 24 matches so far this campaign, Bergwijn has netted 11 goals and assisted 12, illustrating how much of an impact he has on the first team.
His age means that he can still be developed and moulded to fit a certain style of play, something that Jurgen Klopp will be eager to do, should the Reds sign Bergwijn in the summer.
Everything points towards a move to Liverpool, given that he would fit the team well - although would most likely be a back-up option - and that he's affordable, with a market value of around £30m. Premier League action is also just what a player of his calibre needs at this level if he wants to become the best he can be.
