(Reuters) -Australia spinner Adam Zampa says he is below his best at the Champions Trophy but will still be ready to take big wickets in the semi-final against India on Tuesday. Zampa took 2-48 in the washed-out group match against Afghanistan and 2-64 in the five-wicket win over England in Lahore to help Australia reach the last four of the ODI tournament.

History weighs heavily against them but India would rely on a potent spin battery and familiarity with the conditions to break the knockout jinx against an undermanned Australia when the two formidable cricket forces clash in the Champions Trophy semifinal here on Tuesday.
