Who will succeed and fail under Jurgen Klopp at Liverpool?

Here Press Association Sport assesses how the current squad might fare in Klopp's system.

READY

Fitness is a key component in Klopp's system but aligned to technical ability. He wants players to run hard but be able to immediately take advantage of errors such pressing creates. Those players who appear best suited to that include: Danny Ings, Christian Benteke, Daniel Sturridge, Roberto Firmino, James Milner, Jordan Henderson, Joe Allen, Nathaniel Clyne, Mamadou Sakho, Alberto Moreno.

WORK TO DO

Technical ability alone will not be enough to survive in a Klopp world, where double training sessions are far from infrequent. There are a number of players who may have to up their game, but being of a young age will be an advantage to most: Philippe Coutinho, Divock Origi, Jordon Ibe, Joe Gomez, Adam Lallana, Jordan Rossiter.

STRUGGLING

It would not be a surprise to see some of the older members of the squad struggle to adapt to new methods. These are likely to be the the less technical players who have age or physicality against them: Kolo Toure, Dejan Lovren, Lucas, Emre Can, Martin Skrtel.

REPLACEMENTS

Liverpool's owners Fenway Sports Group believe Klopp will get more out of the existing squad than Brendan Rodgers did and early suggestions are the German is happy to work with the players he will inherit. However, he will inevitably need some new additions during his first year in charge and it would be no surprise to see him return to former club Borussia Dortmund to cherry-pick those who served him well in the past. Liverpool could do with upgrades throughout their spine, such as: Roman Weidenfeller (goalkeeper), Neven Subotic (centre-back), Sven Bender (defensive midfielder). The likes of midfielders Ilkay Gundogan and, in particular, Marco Reus may still be out of reach though.
