Striker at Old Trafford needs two contrasting wingers (7,3)
I believe the answer is:
cricket bat
'striker at old trafford' is the definition.
(bat striking balls at Old Trafford Cricket Ground)
I don't understand how the remainder of the clue works.
(Other definitions for cricket bat that I've seen before include "that's used in test" , "One used to glance" , "One used for hitting" , "requirement for four or six, perhaps?" , "might be found in the pavilion" .)
