Matthijs de Ligt (OVR 85 - POT 92)
Still finding his feet at Juventus, it's easy to forget Matthijs de Ligt is just 20 years old.
The centre back is set to be one of the brightest talents in world football, after leading Ajax to the Champions League semi-finals aged just 19.
Joe Gomez (OVR 83 - POT 88)
It's hard to tell how good Joe Gomez actually is, with the 23-year-old having the honour of playing alongside Virgil van Dijk at Liverpool.
Blessed with great pace, and comfortable on the ball, the young England international has a bright future ahead of him.
Ruben Dias (OVR 82 - POT 87)
Arriving for big money (£48 million) in the summer, Ruben Dias has formed an excellent partnership with John Stones.
On Career Mode, it'll be likely you'll have to wait for a year to sign for Dias, where he could be around an 83/84 OVR.
Jules Kounde (OVR 81 - POT 87)
A young star you may not have heard of, Jules Kounde is making waves in La Liga and on Ultimate Team!
The 21-year-old moved from Bordeaux to Sevilla for around £23 million, and made a huge 40 appearances last term as Los Palanganas won the the Europa League once again.
Dayot Upamecano (OVR 80 - POT 90)
One of the hottest defensive prospects in world football, it was a surprise to see Dayot Upamecano sign a new contact at RB Leipzig this summer.
We'd still anticipate the French international to be in demand next year, so you better act fast in Career Mode.
Eder Militao (OVR 80 - POT 87)
Patiently waiting for his opportunity at Real Madrid, Eder Militao is likely to come in for 34-year-old skipper Sergio Ramos in next two years.
With a potential of 87, bringing in the Brazilian would be a very smart signing on Career Mode.
Pau Torres (OVR 80 - POT 86)
Part of the new-look Spanish national team, this could be an interesting campaign for Pau Torres, culminating with the European Championships.
With Villarreal signing Dani Parejo, Francis Coquelin and Etienne Capoue - keep an eye on El Submarino Amarillo this term.
