Given Raggett's injury record, it would be very risky to bring him back, even if he should be good enough for League 1. If we got Vyner back, would we play him at CB, or just hope that he would be better at right back a division down?
There is a bit of a contradiction that Warney likes to play 4-5-1 AND wingers who hardly ever score, possibly because he was one himself later in his career. Basic tactical mistake there, because if you play that formation, you need wingers, and midfielders, who are regular scorers .
