The problem with Royal is he does not have the nouse to play as a centre back. In the Villa game TV here highlighted how his positioning was all wrong for what ended up being a narrow offside goal. I'm no fan of Dier, but he has played the position. If Royal was good on the ball and excellent in picking a pass it would be different, but I see no sign of that. He is more likely to try an outrageous flick that gifts a goal imho. If you are Bournemouth watching today's game, and then see the same back four, aren't you licking your chops? To your point, giving a young player a chance might pay off unless they really are poor. I remember Paul Miller making a solid debut away at Arsenal as a 19 year old ....
