Vyner should be captain as he is more of a leader than Knight. His position allows him to bark out instructions and encouragement. Then there's McCrorie who is vocal and can lead.
Poor old Cornick who dont af get some criticism should play up the middle at c/f with Conway or Wells circulating around him. He has shown that if given the ball to feet, he can shift his arse and out pace defenders. Get him muscled up in the close season and let him loose. Can't play in any other position effectively.
As to Mehmeti, he looks to have improved somewhat in recent games. Although on Saturday he did delay shooting a couple of times when he could have tested their keeper.
