Even with Spann out de squad I think we have ample cover for all positions given the 4-5-1 system we play. Although I think defensive midfield is the area we are a bit thin given we play with two in our current system. Spann was the perfect sub there like we saw in the Bahrain match. also he was good cover for Gray or Edwards so his loss affects the balance a bit.
GK (1): Jack Backup: Shaka, Ince
Right back (1): Gray Backup: Edwards, Sancho, Atiba
Center back (2): Tallest, Dog Backup: Sancho, Cox, Atiba, Gray
Left back (1): Avery Backup: Sancho, Cox
Defensive midfield (2): Birchall, Whitely Backup: Theobald, Yorke, Sancho (?)
Attacking midfield (1): Yorke Backup: Latas, Theobald, Whitely
Left wing (1): Samuel Backup: Wise, Glen, Jones
Right wing (1): Edwards Backup: Samuel, Jones, Birchall
Striker (1): Stern Backup: Jones, Scotland, Glen, Wolfe
Doh forget we have 23 men and only 18 can make the match squad so by definition we have ample cover already.
My 7 subs would be: Shaka, Sancho, Latas, Theobald, Wise, Jones, Scotland
The 5 men to miss out from the 23 are: Ince, Cox, Atiba, Wolfe, Glen (hard luck Glen but given his lack of match fitness who would you drop instead?)
