Birmingham look a pretty limited outfit from the little Ive seen of them in the last couple of years, their main threat seems to be long balls and set pieces into Jutkiewicz who is a big, physical old school lump of a Dyche/Allardyce style centre forward.
If selected, THB will doubtless pick up a few lumps and bumps but also some good experience of playing this kind of opponent.
But we need to show them due respect, we have come a cropper against teams like this in the not to distant past - Wigan, Middlesbrough, Wigan again....
