It's a bit parallel universe on here imo, in that we apparently have to be 'so careful' giving young players game time & 100s of people have said how it's such a 'risk' to even give them 10 mins, then we stick a short, 19 year old cb with no pace in the team, regularly, & most people are totally ok with it, some even suggesting he should be a key figure for next season .
Centre back is a far more harmful position for a kid to fit in, compared to attack. If an 18-19 year old cb can play lots, then a 16-17 year old winger can sure as fuck play a few minutes here & there.
I think you are dead right about Braaf, he is here for his own development, so he will put up with it for a short while, then fuck off to Dortmund or somewhere, if he doesn't get a shot & they will play him & see.
I don't know if he's got what it takes or not, but he's sure enough got talent, so get him on the pitch, just for a cameo here & there, to give him a reason to think he has a future at the club. No lose situation by doing that, especially if extra subs are allowed next season.
