Jurgen Klopp has benefited from incredible mobility in the middle of the park throughout his tenure at Anfield.
The 4-3-3 system which delivered domestic and European success for Liverpool was founded upon the legs of those in midfield, with Jordan Henderson and James Milner already at the club upon his arrival in 2015.
Offensive contributions would be provided by those occupying the flanks - such as Trent Alexander-Arnold, Andy Robertson, Mohamed Salah and Sadio Mane - while the centre of the field showcased strength, balance and security.
The running ability of Henderson, Milner, Gini Wijnaldum, Naby Keita and Alex Oxlade-Chamberlain was undeniable, with each player able to cover excessive ground when required.
Brendan Rodgers - former Reds boss - once elaborated on the difference between using a midfield two and a midfield three, highlighting player profiles as key.
"The two no.8 players have to have the capacity to control but also to run, and get forward, and get back in," Rodgers said. "They have to have the capacity to play in that corridor. If they can't do that, it becomes difficult. You would then maybe switch to a midfield two, because those movements are more side to side."
Liverpool have possessed the necessary midfield qualities to use a trio throughout Klopp's time at the club, but links with Florian Neuhaus suggest that a switch might be on the cards.
The German midfielder is a capable performer and he's strongly tipped for a transfer, but his running ability seems to be different to the typical player that Liverpool chase.
As shown below alongside a select few Bundesliga players across several positions, Neuhaus is not the most outstanding when it covering ground via sprints and intensive runs on a per-90 basis, based on this season.

The 24 year-old still covers a fair amount of distance and his usage of the ball when in possession is impressive, but he does not seem to be the athletic runner that Liverpool have had in past years.
His potential arrival alongside Thiago Alcantara's signature last summer suggests a possible change in formation, with the Spanish international used to performing as part of a pairing while at Bayern Munich.
Mobility isn't Thiago's biggest strength and the same could be said for Fabinho, who was part of a two at AS Monaco before moving to Anfield in 2018.
Both Thiago and Fabinho have showcased an ability to adapt since moving to Merseyside, but the two - alongside Neuhaus - have a history of forming part of a duo rather than a trio.
Klopp could ultimately end up following the words uttered by Rodgers during his time in charge, by using a midfield duo rather than a trio next season as the Reds look to reclaim their English crown from Manchester City.
