First Rare YA Player And Some Questions

I tried to get an image but it doesn’t show the players skills.

Oh well. He’s 15 + 65 days. 5 defending, unknown potential. 7 potential scoring. All other specs unknown. Passable player overall.

Scoutrick (previously Rate My Academy) gave him a 3006 rating.

The previous player I’ve been focusing on is age 15 + 106 days, rates 2695, and has passable potential in scoring, passing, and winger. He is unpredictable.

Since I don’t want to mess this up, how would you proceed?

Before I got this new player I was focused on player number 2. His scoring is finished so I’ve been focused on putting him as the only forward and putting 5 defenders with 2 defenders to maximize the passing experience my player received. Then, I would do similar for training his winger.

Should I quit worrying about this 2nd player and focus on the new rare player? If so, how should I go about it? And is there an optimal way to train both?

Thanks!
