Jurgen Klopp is expected to perform considerable surgery on Liverpool’s squad this summer in a bid to turn them into title challengers next season.

Liverpool have been miles off the pace this year with the current batch of players interrupting glimpses of brilliance with long periods of mediocrity.

Landmark wins, and brilliant performances, over Manchester City (twice), Chelsea, Manchester United and Southampton this season have showed what can be achieved under Klopp but his side are reduced to resting all of their silverware hopes on winning the Europa League.

Klopp turned Borussia Dortmund into a Bundesliga giant in seven years as coach and is likely to begin his transformation of Liverpool by gutting the current squad and bringing in a wave of new talent. Here Football Insider examines some of the possible arrivals.

Liverpool are keeping close tabs on Polish star Piotr Zielinski

Piotr Zielinski

Age: 21

Clubs: Empoli (loan), Udinese, Zaglebie Lubin

Club appearances: 78

Club goals: 3

International appearances: 11

International goals: 3

Possessed with quick feet and an even quicker mind, Zielinksi has emerged as one of the hottest prospects in Italy. The 5’8” Polish midfielder often relies on his skill and touch to navigate past bigger and stronger opponents. Has the mobility to play out wide or just behind the striker, but prefers to dictate play from the middle of the park. Liverpool have already sent scouts to watch Zielinksi but at 21, the Pole still has plenty of room for improvement and would not be the instant impact player Liverpool so desperately crave.

Sadio Mane, Southampton, Manchester United

Saido Mane

Age: 23

Club: Southampton, Red Bull Salzburg , FC Metz

Club appearances: 174

Club goals: 63

International appearances: 29

International goals: 8

Provides blistering pace and an eye for goal, but has seen his stock fallen after a tremendous first season-and-a-half in England. The direct winger is a handful for any defender, but has struggled to build on the 10 league goals and four assists he managed last year. He remains an attractive option however and has attracted the gaze of other Premier League clubs like Manchester United. Capturing his signature might depend on where Liverpool end up this season, with his current club Southampton one place above the Merseysiders in the league.

Chances of joining Liverpool: 4/10

Marc Bartra

Age: 25

Club: Barcelona

Club appearances: 101

Club goals: 5

International appearances: 6

International goals: 0

A name often on the lips of Liverpool supporters during transfer windows, but has never really come close to leaving his boyhood club. However at 25, the agile and clever centre-back has failed to maintain a place in Barcelona’s eleven and has just three league starts this season. Despite his limited chances, Barcelona has so far strongly resisted any potential move away. With his contract due to expire in the summer of 2017 and Javier Mascherano, Gerard Pique and Jeremy Mathieu above him in the pecking order, Bartra may well feel the time has passed for him to be sat watching from the bench.

Chance of joining Liverpool: 7/10

Marc-andre ter Stegen

Marc-Andre ter Stegen

Age: 23

Club: Barcelona, Borussia Mönchengladbach

Club appearances: 167

Club goals: 0

International appearances: 4

International goals: 0

Young, strong and level-headed, ter Stegen is another Barcelona youngster who could be tempted away in the hope of a regular  starting role. Has made 19 appearances this season, but 15 of those have come in the cup competitions and the 23-year-old has played second fiddle to Claudio Bravo in La Liga. Liverpool’s Simon Mignolet may have just signed a new long-term deal, but has failed to shake off his tendency for howlers. Klopp may have sanctioned a new contract for the blundersome Belgian, but recognises the team need A-list competition for the current No1.

Chance of joining Liverpool: 6/10

Manchester United are on the trail of Inter Milan striker Mauro Icardi

Mauro Icardi

Age: 23

Club: Inter Milan, Sampdoria

Club appearances: 131

Club goals: 59

International appearances: 1

International goals: 0

Has proven himself to be a natural goalscorer after following up his 22 league goals last season with 12 strikes already in the current campaign. The centre-forward carries a heavy burden in an average Inter Milan side and was handed the captaincy at the start of the campaign at just 23. His speed and potency mean would not come cheap, with his price mooted at around £35million, but he could provide the perfect target for Liverpool’s current South American gems Roberto Firmino and Philippe Coutinho.
