Jack Leach is not just focusing on getting the wicket of Steve Smith as he prepares to make an expected Ashes debut in the second Test at Lord's.

Leach has replaced the struggling Moeen Ali in England's 12-man squad, after Joe Root's side suffered a 251-run defeat at Edgbaston.

Australia's superb comeback from 122-8 in the first innings was led by the talismanic Smith, who rescued the tourists with a stunning knock of 144 and then followed it up with 142 in the second innings as they took command.

Smith's average against left-arm spin is a much less impressive 34.9, but Leach insists he is not placing any extra importance on claiming the wicket of Australia's former captain.

"It's the same for every batter. I want to get every batter out. Yes, there's Steve Smith but there's 10 other guys as well and I'll be focusing on all of them."
