Well, yes, if you're the Welsh manager then you go for (a), obviously... (That was kinda my point... i.e. that he put the interests of the Welsh team ahead of the welfare of the player...)
P.s. I wasn't talking about him "picking up a little knock" either... That can happen to any player, regardless of their match fitness levels. I was talking about the risk of playing a player who has had zero training for a week....
Anyway, all in the past... The future is bright... Hopefully!
