I think the use of the term 'trafficked' isn't great. The difference between these lads getting moves to a relatively big club with a good wage is a very different world to someone getting actually trafficked.
That said, we do owe them a duty of care when they get here and I think there's been a dereliction there. They clearly weren't properly scouted (obviously in addition to being purchased based on Bord's AI bollocks). If they had, we'd have known if there was something worth teasing out through exposure to u21 football.
As Champers says, what on earth were we doing bringing in another RB when we were stocked with them. Although, when you look that Seriki was in the first team, Sachdev injured, Curtis out on loan etc, then there were definitely opportunities for him. I worry about the culture of the club that we don't seem to have a pathway for foreign under 21s in addition to local ones.
