The Reds have already brought in Naby Keita, Fabinho and Xherdan Shaqiri but remain eager to strengthen further before the window closes next month

Another player targeted by Liverpool in the past – they bid for Julian Draxler when he left Wolfsburg for PSG in January 2017 – and one who could well be on the move this summer.

Draxler can play wide or centrally, and has good pedigree from his Bundesliga days with both Schalke and Wolfsburg.

With PSG potentially set to spend big again this summer – Eden Hazard and N'Golo Kante have been linked – the opportunities for the German international could be further limited.

Again, he would cost a lot, but we know that Klopp admires the 24-year-old.

Another teenager from the Bundesliga, and one who has made a big impression over the last 18 months. Kai

Havertz, 19, has performed well for Bayer Leverkusen and has attracted scouts from across Europe. Liverpool are among those who have noted the forward's progress, making regular checks on the German youth international.

It may be a little soon for him to be considered as a possible first-teamer for the Reds – especially at the fee Leverkusen are likely to demand – but his talent and versatility would definitely appeal to Klopp.

One to keep an eye on, for sure.

It's no surprise to see Domagoj Vida linked with numerous clubs following his World Cup exploits with Croatia. The ponytailed centre-back stood out alongside Dejan Lovren as his side enjoyed a remarkable run to the final, and looks set to earn a move off the back of his performances.

Liverpool have been linked by the Turkish media, but Goal understands that the club are unlikely to recruit a central defender this summer. Virgil van Dijk, Lovren and Joel Matip are the senior options, with Joe Gomez and Ragnar Klavan offering ample cover.

At 29, Vida does not fit the profile of player Klopp and his recruitment team are looking to bring in.

Getty4Julian Brandt | Bayer Leverkusen

Another favourite of the Reds' recruitment team, Julian Brandt was on the club's radar throughout the 2016-17 season, before they eventually plumped for a free-scoring Egyptian from Roma called Mohamed Salah.

That turned out well but, with depth wanted (and needed), there is still an interest in how the 22-year-old is progressing in the Bundesliga.

Brandt can play anywhere across the attacking line – a trait valued by Klopp – and was one of the few players to emerge with credit from Germany's terrible World Cup campaign.

He'd cost a lot, mind, and would not be guaranteed a starting berth.
