Overall, Juventus have spent £961m (€1.08bn) in the past decade compared to Manchester United's £914m (€1.03B).
But the way Juventus have conducted their transfer activity has been far superior to Manchester United.
Juventus famously assembled arguably the best midfield trio in Europe with Pogba, Pirlo and Vidal for just £10m and there have been very few examples of expensive flops over the last six to seven years, at least.
The Bianconeri's work in the free transfer market has to be commended. Pirlo, Khedira, Alves and Pogba are or were top-class players brought in for absolutely nothing.
And when the Italians have splashed the cash, they have made sure it was worth it as well. Higuain scored 40 goals across two seasons before Juventus loaned him to AC Milan for €18m, with a view to selling him permanently for a further €36m.
The signing of Cristiano Ronaldo was out of character for Juve, as paying over £100m for a 33-year-old doesn't reflect their previous transfer policy. However, Ronaldo is regarded by many as the best player in the world and if he can deliver the Champions League to the Italian giants, it will be considered a shrewd move.
Manchester United's marquee signings have not always fared so well. Star names such as Di Maria, Falcao and Alexis Sanchez have all flopped at Old Trafford, while many of their other big-money signings have failed to live up to their price tags, with Pogba being the best example.
Promising younger signings who came at a heavy cost have often struggled to develop, with Martial and Shaw two young men who have laboured for long periods at the club.
In terms of sales, Juventus rarely make losses on a player. The easiest comparison to make between the two clubs would be Pogba. United let him go to Juve for free before buying him back for a world-record fee, earning the Italians a near-£90m profit.
Overall, the Italians have recouped £624.4m (€703.75m) over the past decade whereas United have received just £304m (€342m) during that time.
Juve's net spend has thus been just £337m compared to Man Utd's £610m.
Overall, the fruit of Juventus' labour has been clear. They have won seven successive Serie A titles and reached two Champions League finals in four years - all while having a substantially lower wage bill than Man Utd.
The Red Devils, on the other hand have not won the Premier League title since 2013 and have not progressed past the quarter-finals of the Champions League during that time.
On the pitch, the two teams are light-years apart right now and this can be put down, at least partially, to Juve's superior business in the transfer market.
