Liverpool are lining up a move for Bayern Munich's Mario Gotze, who is one of six stars to have made the Reds' summer shortlist.
Manager Jurgen Klopp will hope to reunite with former Borussia Dortmund disciple Gotze, but Joe Musker of Gianluca Di Marzio's website reported Raphael Guerreiro, Ben Chilwell, Piotr Zielinski, Granit Xhaka and Marc-Andre ter Stegen are also being targeted.
Gotze left Signal Iduna Park for Bayern in 2013 after Der FCB activated his £37 million release clause, but competition for places at the Allianz Arena has seen the German's development stagnate since then.
It was under Klopp that Gotze first announced himself as a name to watch at Dortmund, and former Liverpool defender Jamie Carragher has tipped the playmaker as a worthy investment this summer:
For Liverpool to add such a wide array of talent, however, there may first have to be departures at Anfield. In that sense, Gotze might be expected to challenge for the same spot in attacking midfield the likes of Philippe Coutinho and Adam Lallana have occupied this term.
The central-midfield duo of Zielinski and Xhaka both have understandable connections to Klopp. The Liverpool chief invested in Polish talent during his time with Dortmund, developing the likes of Robert Lewandowski and Lukasz Piszczek to great success, while Borussia Monchengladbach's Xhaka has starred in the Bundesliga.
The Daily Mail's Simon Jones reported last week that Liverpool were set to open talks with Udinese, the parent club of Zielinski, who has enjoyed a fine season on loan with fellow Serie A side Empoli.
Xhaka may make for an easy sell, too, considering the Switzerland international has made no secret of his desire to join the Premier League ranks.
He recently spoke to German broadcaster Sky Sport and admitted (h/t Metro's Will Giles): "I think everybody has a dream. Everybody has a childhood dream and that’s my childhood dream. If my dream comes true, it remains to be seen. At the moment I cannot say how realistic it is."
It's hardly a secret Mignolet's mistake-laden season has caused some concern at Anfield, and former Gladbach ace Ter Stegen is thought to be a realistic target after struggling to feature at Barcelona.
It's been almost two years since the German completed his move to the Camp Nou, but Ter Stegen has made just four league appearances for Barca, leading Spanish daily Mundo Deportivo to note the club's concern over his future (h/t Football Espana).
What's more, Ben Smith of BBC Sport has said Mignolet's future at Anfield is far from secure:
It's mentioned that left-back is a key area for recruitment in Klopp's understanding, which is where Lorient defender Guerreiro and Leicester City youngster Chilwell come into the equation.
Liverpool were disappointed to lose emerging Joe Gomez to a serious knee injury at the start of this season, but Portugal international Guerreiro, 22, or England under-21 Chilwell, 19, could provide young alternatives.
