There are no shortage of midfielders in this category. Gio Reyna, Yunus Musah, Malik Tillman, Johnny Cardoso - all entered the summer with very obvious question marks following their names. Some were answered on the field, others were answered via their transfers and others will be addressed in the months to come. All, though, made a move towards answering them.
Starting with Tillman and Cardoso, who were part of the Gold Cup roster. The former shone throughout this summer's tournament before making his big move to Bayer Leverkusen.
Early-season chaos has resulted in a coaching change, which does throw a wrench in things, but Tillman should remain a key part of the club's plans regardless of who picks the team. Cardoso, meanwhile, struggled with injury this summer, but already looks like a key figure for Atletico Madrid, one of the best clubs in the world. Translating that to the USMNT is the next test, but he can cross that bridge soon.
As for Reyna and Musah, both missed out on Gold Cup duty, and both entered the summer with spots threatened after being in the squad for the 2022 World Cup. Musah joined Atalanta on deadline day, giving him a chance to take a leap forward in a new environment that might just be a step up the ladder.
Reyna, meanwhile, took a measured step back, joining friend Joe Scally at Borussia Monchengladbach as he looks to rebuild his career after spending too long on Borussia Dortmund's bench.
And while not a midfielder, someone else with a point to prove is Tim Weah, who moved to Marseille. Clearly a sentimental return to French soccer, one that allows him to continue to retrace his father's massive footsteps. Nostalgia aside, this is an interesting move for Weah, though, as he joins a team that is seemingly already pretty well-stocked with attacking talent.
There are minutes to be earned, of course, whether as a winger or wingback, and Marseille are set to compete in the Champions League this year. Ultimately, it will depend on what kind of role Weah can carve out. He will provide competition for multiple positions on the field and, in the best-case scenario, will win one of them to make the team better.
Now, each of them has to do the hard part. World Cup spots, both in the squad and the lineup, will be determined over the next few months, and they'll largely be determined by form. The competition is fierce and it seemingly evolves by the day. In all likelihood, a few of the names above will be part of it, but much of that will depend on how these transfers shake out.
