Son went from best player on mid team to a new academy type team that is very good. I can see what he needs to work on but not sure how to help him.

He's U13. This new club is run "academy style" There are around 30 kids on the club for his age group. There are probably only 5 new players, everyone else was there last year. Which I take as a good sign. The 1st and 2nd teams are fluid for tournaments so you can earn your spot on the first team and lose it. They release the roster for the tournaments a couple weeks before so you know if you "made it". Although the 1st team plays ECNL and the 2nd team plays EA. Not sure if those rosters are fluid or they are locked in for the year.

Anyways, the top 5 or 6 kids are quite a bit better than the rest. Then there is honestly a pretty minimal gap between kids 10 and 30. They are all good. My son is honestly in the 20-30 range right now. Which I totally expected and he did too. He loves it though. The coaching is great. The teammates are great so far. It's been great. He told me he wants to make it to the 1st team though. Where he lacks, from what I can tell are a few things that I'm not sure how to help him with or if I even can help him with.

1. Just physical quickness or acceleration. If it's a long run, where he's got to go 30 yards he's fine. He can hang with most of them. It's the quick short bursts back and forth that he is pretty far behind imo. Like pressing, a short burst to a 50/50 ball. Just getting up to top speed quickly, changing direction, and getting up to top speed again quickly. I figure getting into plyometrics, and some sprinting drills will help this. But any other tips or ideas?

2. He's smaller than everyone. I'm 6'2", my 2 brothers are 6'4" so I figure he'll catch up at some point.

3. Just doing everything faster. Taking first time shots, instead of control, dribble, shot, for example. There just isn't time with these better kids to take that extra touch. Or taking a first touch and immediately making a decision. Always seems to be taking 1 too many dribbles, or holding on just a 1/2 a second too long. I honestly figure this will start to work itself out with more time against better players. Other than that how can I help him with being more decisive and quicker?

4. Spacing and movement off the ball. Often times seems to get in the way. I kind of take this as him playing with worse players in the past and not trusting them. Which he doesn't need to do now. Any resources to help with this? Where to go? When? Why? I'm a basketball player so soccer is fairly new to me and I'm not confident I give him the right info.

I know he's only 12, and a lot of this will work itself out with his coaches and puberty. But he's eager and wants me to help him work on things. So any tips or resources are appreciated.
