Fill in footsteps at Edgbaston (4)
I believe the answer is:
sate
'fill' is the definition.
(I know that fill can be written as sate)
'in footsteps at edgbaston' is the wordplay.
'in' indicates a hidden word.
'SATE' can be found hidden inside 'footsteps at edgbaston'.
(Other definitions for sate that I've seen before include "Quench" , "Fill totally" , "Stuff with teas" , "Malaysian dish" , "Fill to satisfaction" .)
