This is another challenge that might take more than three seasons to succeed at. Firstly, there is the hard task of taking a team from the second (or lower) division to a top European league. The player should spend the FC 25 Coins following seasons on solidifying the team's spot in the first division.
Finally, getting to a Champions League promotion spot and buying the players who will make the team competitive in that tournament is a challenge in its own rights. It's more than worth the effort, though. Reaching the pinnacle of European soccer with an underdog team is the ultimate Cinderella tale, and one of the most satisfying things to do in FC 25.
This is probably a FC career mode challenge that requires the most patience of them all. Given the fact that youth academy players with high potential usually start wanting to ascend to the first team when their overall ratings are at about 65-69. it means that in order to fully develop a title-winning team with these footballers, players will have to spend at least four seasons rotating a low-rated squad to allow the youngsters to meet their potential ratings.
Although it might take about seven or eight seasons to complete the project, the end result is always extremely satisfying. Youth players with high potentials tend to outperform any of the existing, real-life footballers, and so an entire team of fully-grown, high-potential academy players in Career Mode is as close to an unbeatable side as it gets in FC 25.
This is an extended version of the "win five European leagues" challenge. Trying to become a national champion on five continents is a great adventure and a perfect opportunity to freshen up the gameplay when it gets stale. The best way to enjoy this challenge is by starting in South America or Asia. Next, they can ultimately make their way to Europe. Opting to play career mode like this is also a great way for cheap FIFA 25 Coins players to educate themselves about some of the lesser-known, more "exotic" soccer leagues.
