So Sig and Townsend have been dropped - Tim said they were available. So looks like we preferred to have 2 defenders on the bench over them. Odd decision.
Not really - you need to cover all bases with your 7 subs so normal to have 2 defs on the bench. Capoue is a defensive CM sub and Defoe covers the two CF. So I guess you could say that CHadli and Holtby have been picked in preference to a non-match-fit Townsend and Siggy
