<p>This summer's transfer window is poised for dramatic developments leading up to its closure on September 1. Several high-profile deals have already been secured, with expectations of additional significant transactions in the following weeks. While top-tier players at their peak are expected to switch clubs, there is a growing trend among teams to invest in emerging talent. Clubs are shifting their focus to acquiring promising young stars, aiming to lower the average age of their squads and make long-term investments.</p>
<br />
<p>Argentinian prodigy Franco Mastantuono recently completed a €45 million transfer to Real Madrid, and other noteworthy young talents may also make moves this summer. Brazilian sensation Estêvão, just 18, has moved to Chelsea from Palmeiras. Young Greek forward Charalampos Kostoulas from Olympiacos has transferred to Brighton for €35 million, and Ajax defender Jorrel Hato has also signed with Chelsea. But if we take a look back through history, who are the most expensive teenage transfers ever? <em>Transfermarkt</em> presents a compilation of the top 30. This list features numerous youngsters who blossomed into global superstars, alongside some who couldn't meet their anticipated potential.</p>
<br />
<h2>The Most Expensive Teenage Transfers of All Time</h2>
<br />
<p>Leading the list is Kylian Mbappé, who transferred from Monaco to PSG for €180 million in the summer of 2018 at just 19 years of age. This remains the second-highest transfer fee ever, surpassed only by Neymar's transfer to PSG the prior summer for €222 million. Mbappé has certainly justified his hefty price tag, becoming the club's all-time leading goal scorer, although it is a bitter pill for PSG to swallow that they let him leave on a free transfer six years later. In second place, Atlético Madrid's €127.2 million acquisition of João Félix from Benfica in 2019, when he was also 19, has not quite gone as planned.</p>

<br />
<p>The third most costly teenage transfer involves Juventus signing 18-year-old Matthijs De Ligt from Ajax in 2019, following his captaincy of Ajax to the Champions League semi-finals the previous season. Fourth on the list is Chelsea's acquisition of Roméo Lavia from Southampton for €62.1 million in the summer of 2023. Fifth is Manchester United's €62 million signing of Leny Yoro from Stade Rennes last summer, while sixth is Anthony Martial, who joined United for €60 million from Monaco back in 2015. The early promise displayed by Martial, notably through his stunning solo goal against Liverpool, has since seen his career at United take a downturn.</p>

<br />
<p>Seventh and eighth positions belong to transfers to PSG last summer: €59.9 million for midfielder João Neves from Benfica and €50 million for Désiré Doué from Stade Rennes. Ninth and tenth positions are occupied by Real Madrid signings, underscoring 'Los Blancos' recent shift in transfer strategy. Ninth is Endrick, who was signed from Palmeiras for €47.5 million last summer, while the tenth spot is filled by the fresh arrival of Argentinian star Mastantuono from River Plate for €45 million.</p>
