SYDNEY, Jan 3 (Reuters) - Captain Ben ‌Stokes joked on Saturday that nobody really knows what they are doing when they inspect a wicket before ‌a test match, as he continued to ponder England's final line-up for the fifth Ashes clash.

England ‌named a 12-man squad for the clash on Friday with seamer Matthew Potts and spinner Shoaib Bashir likely vying for the one spot on the team - depending on what was expected from the pitch.
