The Ashes: Alastair Cook hints at England bowling changes

England captain Alastair Cook explains why England may make changes to their winning Ashes side ahead of the second Test at Lords.

Cook says he tries to be as "loyal" as he can to his players but admits "sometimes you have to make tough decisions" and pick different players according to the demands of the pitch "for the good of the side".

England won a thrilling First Test at Trent Bridge by just 14 runs.
