Liverpool take on Manchester United on Sunday looking to go level on points with their fierce rivals at the top of the Premier League.
The match is arguably the biggest test in the Reds' defence of their Premier League title to date, with the Old Trafford club appearing to have hit form over the last six weeks.
Both teams have talented players in their side but, over the course of the season, squad depth could well prove to be the difference in the title race, particularly with sides more susceptible to injuries during a condensed campaign.
One good way of judging a team's squad depth is to take into account the overall valuations of a side.
In terms of Liverpool and Manchester United, there is a clear winner here, with the Reds valued at nearly £280m more than their rivals.
Valuation site Transfermarkt has given Jurgen Klopp's squad a valuation of €1.1bn, which is the highest in world football, beating second-placed Man City by €86m.
In comparison, United have the ninth-most valuable squad in football at €765.35m.
Intriguingly, there is an argument that United have been undervalued, with Marcus Rashford given a worth of €80m.
In comparison, CIES Football Observatory recently released new valuations that argued Rashford was the most expensive player in the world and worth double Transfermarkt's value at €165.6m - which would give United's squad a worth of over €850m.
One area that sees the Reds having a greater squad value is due to having three players valued at over €100m by Transfermarkt.
Mohamed Salah and Sadio Mane are both valued at €120m, with Trent Alexander-Arnold worth €110m.
In contrast, United's most valuable player on Transfermarkt is €90m-rated Bruno Fernandes.
Just two Old Trafford stars are worth over €70m, while seven Reds players are valued over that price.
Of course, the Reds will be without one of these players on Sunday, with €80m-rated Virgil van Dijk out injured, as is the likes of Joe Gomez, Naby Keita and Diogo Jota, all of whom are worth €40m.
Yet this again shows the difference in United and Liverpool's squad players - by having a higher-end value, the Reds are able to call upon players who are worth as much as some starters at Old Trafford.
For example, €24m-rated Victor Lindelof is a doubt for Sunday's game and could be replaced in the centre of defence by Eric Bailly, who is worth an estimated €17.5m.
In contrast, without Van Dijk and Gomez, the Reds have been able to plug their defence with €60m-rated Fabinho and Joel Matip, valued at €32m.
Unlike United, who have tended to consistently spend large amounts to bring in a big-name player, such as Paul Pogba or Harry Maguire, Liverpool have tended to spread their cost around on various players - with the obvious exception of breaking their transfer record to bring in Virgil van Dijk.
This approach is clearly paying dividends, as they have been able to strengthen their squad as a whole instead of focussing solely on their starting XI.
Perhaps this is just as evident in the impact young players have had on the Reds this season in the face of injuries, with Curtis Jones an example of a player who is now worth €17m thanks to his performances.
Of course, not every player is guaranteed to increase their value in Liverpool's team, but with United's big-money signings like Maguire and Pogba worth much less than what they were brought to Old Trafford for, the Reds' focus on development and smart spending appears to be the smart way forward.
Indeed, there is an argument that United's recent transfer approach has tried to copy Liverpool a bit. Whilst Bruno Fernandes has transformed Ole Gunnar Solskjaer's side, he was not signed for a record amount.
The Old Trafford club then bolstered their squad over the summer with relatively average amounts paid for Donny van de Beek and Alex Telles, whilst the decision to sign Edinson Cavani on a free transfer looks a smart piece of business.
Yet, as the difference in squad values shows, the Red Devils have some way to go before they can achieve the same consistent level of success as their rivals have.
