Liverpool vs Chelsea is one of the truly iconic Premier League fixtures.
While the two global powerhouses are found at different ends of the country, their rivalry has grown to a near derby-like level.
Their clashes are always fiercely competitive, dripping in goals and never far away from controversy.
The pair will meet one again in the Premier League this week as the battle for one of those coveted top-four positions heats up.
As the season ebbs away, both teams will be desperate to get their hands on as many points as possible to ensure they book their place at the top table of European football next season.
Chelsea hold the upper hand at the moment, but a loss this week would see the Reds leap frog them into fifth place.
So, with yet another Mersey-Thames battle on the horizon, we thought we would go about the business of ranking the two squads into seven categories from 'Genuinely World-Class' to 'Sell ASAP' using the handy tools over at Tiermaker.
While Liverpool have struggled to maintain their incredible form this season, there can be no questioning the fact that their squad is littered with world-class talent.
Chelsea, however, are a young side who boast a lot of potential, but no real fully-fledged world beaters just yet.
Virgil van Dijk
Both sides can call upon some real top drawer players, even if they aren't quite world-class just yet.
Not quite world-class, not quite top drawer, but brimming with genuine quality and would make any other team in the Premier League.
Middle of the road
The most populated category on the list is reserved for those handy players who can certainly do a job, but might struggle to string together a run of starts or truly set the Premier League alight.
A smaller contingency of players who might feel hard done by not to get more game time or more respect in general considering what they are capable.
This is when the ranking might start to look a little harsh, but, there is no room for sentiment when it comes to top level football.
The lowest rung on our board. How some of this lot are still at clubs with the pedigree of Liverpool and Chelsea is beyond us.
