agree, but even a few games in U23 (at that time) was enough to see they don't have problem against a few years older players. Also both are playing in attack where you don't need that much in terms of tactical knowledge, and can do with pace and movements to avoid duels. Defenders have to rely on strength as well, while also tactical part is even more important, movements, experience. I don't want to have him on the pitch to have a bad game and than kill his confidence. He will be ready soon, but lets wait for that, test him in U21 and a friendly or two. Maybe some easier game or last 10 minutes when we are 3 up (if that ever happens).
