England coach Brendon McCullum has indicated he is likely to keep faith in out-of-form opener Zak Crawley and play him in the second Test against South Africa at Manchester from August 25, saying one has to think about the "overall package".

Crawley has been going through a prolonged form slump at the top with the 24-year-old opener managing just nine and 13 against the Proteas in the opening Test at Lord's, which England lost by an innings and 12 runs inside three days. The right-hand batter has yet to score a half-century for his country from 10 innings this summer.
