#1 Signal of intent, another welcome young acquisition
When you're a big team like PSG, you need those world-class acquisitions to bolster the ranks. It's why they shocked the world by activating Neymar's €220m release clause to sign him two summers ago and €135m (initial loan deal) for Kylian Mbappe the very same month.
Their eagerness to improve means that when a player of de Ligt's quality is available, they cannot afford to take any chances. Signing him would prove how serious they are about achieving their targets.
For a team with such lofty ambitions, that's just not good enough. So how would he improve them? Well, he takes them to the next level. A bold statement to make, sure. But look at how he has flourished with Ajax over the past twelve months - defying the odds against Real Madrid and Juventus.
A lot of that came down to him leading by example: defensive contributions aplenty and importantly popping up with goals when called upon too. Who can PSG turn to, when their MCN trio are misfiring? No-one stands out. Their existing backline is too shaky and they concede too many opportunities against better opposition, which proves costly as their opponents do take their chances.
de Ligt's arrival would go some way to committing the futures - at least short-term - for their highly-coveted players linked with lucrative moves elsewhere. PSG are good but must invest smartly and completing a deal for the Dutchman would prove money well spent, so they must sign him this summer.
