During the summer transfer window Liverpool and Manchester United have sought after young and talented left-backs to provide a long-term solution to the position.
Manchester United immediately plumped for Southampton's Luke Shaw, remaining steadfast in their pursuit and eventually splashed out £30 million to get their man.
Liverpool have been less determined with their choices, employing what can be described as a scatter-gun approach. For most of the summer they have been enchanted with Alberto Moreno, though were somewhat put off with the price tag Sevilla slapped on their left-back.
Since then they have had an £8 million bid rejected for Swansea's Ben Davies. Rival fans immediately noticed the £22 million difference and asked the question: is Luke Shaw that much better than Ben Davies?
The answer is a resounding no.
In defence both Ben Davies and Luke Shaw recorded similar numbers in the Premier League last season.
In the tackle, Ben Davies and Luke Shaw posted near identical numbers. As per WhoScored, Davies won 2.2 tackles per game, whilst Shaw was slightly down with 2.1.
In terms of how they feared with the rest of the league: Jon Flanagan and Cesar Azpilicueta lead the left-backs with 3.4 tackles; Erik Pieters is second with 3.3 tackles; Leighton Baines and Gael Clichy are third with 2.9 tackles; Danny Rose is fourth with 2.6 tackles; Kieran Gibbs and Patrice Evra are fifth with 2.4 tackles; and finally, next up are Davies and Shaw in sixth and seventh.
In terms of interceptions, Ben Davies made far more than Luke Shaw, averaging 1.9 per game to Shaw's 1.1. However, Shaw counteracts this by being harder to go past; Shaw was dribbled around 0.6 times in comparison to Davies' 1.6.
Despite the massive disparity, Davies and Shaw are actually quite even on this front. Shaw makes less interceptions because he doesn't need to be on the front foot all the time - he has Morgan Schneiderlin and Victor Wanyama covering him.
The same cannot be said of Davies who does not have a designated defensive midfielder in front of him. As a result, he has to step forward to retrieve the ball far more than Shaw has to, leaving himself open.
To put it into context, Schneiderlin made 3.4 tackles and 2.1 interceptions compared to Leon Britton's total of 1.5 tackles and 2 interceptions.
Wanyama made 2.8 tackles and 1.4 interceptions which dwarfs Jonathan De Guzman's 1.2 tackles and 0.8 interceptions.
In attack Luke Shaw enjoys a definitive advantage over Ben Davies as a result of his greater athleticism. When it comes to dribbling, Luke Shaw completed 1.6 dribbles per game - far higher than Ben Davies total of 0.4.
In fact, at an average of 1.6, Luke Shaw is the 11th best dribbler in the Premier League, completing more than the likes of Willian, Wayne Rooney and Samir Nasri.
Consequentially, Shaw has more shots on goal (0.7 per game), compared to Davies (0.3); is fouled more (1.3) compared to Davies (0.7) and has more key passes (1) compared to Davies (0.9).
Having said all that, Luke Shaw is less productive in front of goal. Shaw has never scored a goal in the Premier League despite having 34 shots, meanwhile Davies has scored 3 goals (twice last season) with only 18 shots.
As for assists, Shaw only has only has one (last season), whereas Davies has three (once last season).
A major reason why Ben Davies is able to be more efficient in front of goal, despite having less in his locker is due to his superior in-game intelligence.
Ben Davies was dispossessed on an average of 0.5 times last season, for Luke Shaw this total rockets up to 1.3. Likewise, when it comes to turnovers, Davies has lost the ball 0.8 times, whilst Shaw isn't too far behind on 0.9.
Only Kieran Gibbs, Gael Clichy and Aleksandar Kolarov kept the ball more safely than Davies did at left back.
More alarmingly, Shaw's passing accuracy is quite wayward. He achieved a 79.1% passing accuracy from an average of 40.1 passes per game. In comparison, Davies had a far greater passing accuracy of 84.3% from an average of 48.6 passes.
Of all the left-backs in the Premier League, only Gael Clichy and Leighton Baines passed the ball more securely than Davies. And only Clichy attempted more passes than Davies.
This is more pronounced as Southampton were the Premier League's best in possession with 58.6%, albeit Swansea were third with 57.3%.
There is little to suggest why there is a £22 million price differential between Luke Shaw and Ben Davies. One thought is that Shaw (19) is two years younger than Davies (21).
Secondly, Shaw is likely to play competitive international fixtures for England whilst Davies in all likelihood won't with Wales.
Finally, Shaw seems to have more natural ability than Davies, who simply uses the ball more intelligently and economically. If Shaw was the incorporate those facets into his game, he could become one of the best left backs in the world.
