Relax buddy. The guy is just pointing out that we shouldn't start proclaiming that our RB issues are sorted. We played the same game with Luke Shaw (which went spectactularly wrong, as you know). We need to wait a few years, to see if this guy is genuinely any good (remember, he has barely played first team football for any team), after which we can make an assessment. IMO, we'll need to wait at least 4 years, before we can make a concrete judgement on this guy.
