The early days of Jurgen Klopp's tenure as Liverpool manager were defined by his full-throttle football. Outrunning opponents, squeezing defences and overpowering their opponents were the spine of the club's resurgence under the German.
Klopp's heavy-metal style propelled Liverpool back up the Premier League table and laid the groundwork for what was to come but it couldn't bring long term success.
For all their attacking verve and frenetic energy, there were still weakness at the back and fears they could be caught out by teams sitting deep and hitting them on the break.
Thiago Alcantara will bring something completely different to Liverpool this season
Jurgen Klopp has tailored his style in the last two years to turn the Reds into a winning machine
Getting back into the Champions League at the end of 2016-17 was huge for Klopp's reign and taking his side to the final in Kiev 12 months later showed remarkable and rapid progress.
But in order to be successful and become genuine, long-term challengers for both the Premier League and Champions League, Klopp knew some tweaks had to be made.
Changes to the system became noticeable at the start of 2018-19 when Liverpool embarked on a stunning period of form that took them to the summit of European and domestic football.
There is now a patience to Liverpool's play and they have developed an ability to methodically dismantle teams over 90 minutes, rather than go for the jugular in the first 20.
Make no mistake about it, Liverpool can still steamroll somebody if they want. Trent Alexander-Arnold and Andy Robertson still fly forward and the famed front three are just as menacing as ever.
None of Liverpool's current midfield options have the passing range and intricacy of Thiago
But subtle changes to Klopp's 4-3-3 and the ability to control every area of a match have allowed his side to blow almost everybody away over the past two seasons.
Signing Thiago will only enhance this dimension of Liverpool's system.
Klopp is even more wary this season of teams sitting deep and focusing on defence when they play Liverpool. Although Leeds scored four at Anfield last week, they will be one of very few teams who come out all guns blazing.
It is a boost then that they have recruited a forward-thinking midfielder who can unlock the sternest of defences.
Thiago is a maestro on the ball and can play almost every pass in the book, offering something different to Klopp's existing midfield options.
