I remember early on in the job Wilder saying that ideally he wanted at least 2 players for each position. This puts pressure in the form of competition on the player who is first choice and also allows him to rotate the squad or rest players and means we have cover if players get injured or lose form. I would have thought that Stevens is cover/competition for Lafferty/Freeman. Nathan Thomas is probably a replacement for Chapman who will be used as an impact substitution if we need to change things during a game. At the moment we have only Wright, JOC and Bash who are centre halves (assuming Wilson leaves and EEL is not re-signed (which personally I do not think we should do)) so I think CW will be looking to sign at least 2 CH's especially as there must be a question mark whether Wright can play at Championship level (though personally I think he will be able to but probably not as first choice). We have Duffy and Caruthers doing the number 10 role but no cover for Fleck or Coutts unless Bash moves to midfield but he is not really a replacement for either of those. I presume that Holmes (if we get him) is looked at as cover for them but we probably need at least one more. Up front we have plenty of competition for 2 places but there are definitely question marks over Hanson and Clarke at Championship level, Lavery is untried at that level (though I think he will be good) and even Billy does not have a great track record there so I think we will need another recruit hopefully with strength and pace. I am sure CW AK and the team will know exactly who they want.
