Looking ahead for the USMNT here's what needs to be addressed before we go into 2022 qualifying.
1. Left back. Villafana is 28 and not good enough. I don't think in 3-4 years he'll be any better. There is another option here I'll tag on in the next point.
2. Sorting out the Centerbacks. US has already 1 great young CB in John Brooks. They have a few interesting prospects including Tottenham's Cameron Carter-Vickers, Chelsea's Matt Miazga, and Manchester City's Emerson Palmer-Brown. Which leads to a potential LB solution, which is the US doesn't go with a traditional 4 man back and goes with a 3 man back. Especially since all those CBs are athletic.
3. Get hyped about potential in the midfield. Here's where things look most interesting for the US. Already with a talented young guy in Acosta, add in McKennie, Gonzalez, Adams, Hyndman, Gooch, and many more interesting options. But that's not factoring the winger/attacker types in Pulisic, Carleton, Perez, Wright, and more. Or the potential guys who may need a club move first to regain some shiine like Zelalem and Green. Or the who knows like De la Torre. The point is that there's a very good chance we could actually have an issue with finding places to play guys in the midfield and I'm really looking forward to thatafter the disaster of our midfield this year.
4. Sort out goalkeeping. Odds are 1 of Gonzalez, Horvath, or Klinsmann amounts to something. Add in a chance that someone like Steffan could turn it around after a relative fail in Europe. Hamid looks to be moving to Europe this winter and he has all the ability to be a quality keeper and maybe a trip to Europe will enhance his game. 31 isn't old for a keeper so he could be the one next WC.
5. Letting Pulisic play with Wood/Sargent/Morris etc. They'll be our attacking force going forward. We need to figure out who'll be attacking with Pulisic.
