The shortest is Twenty20 (20 overs, T20), then One Day Internationals (50 overs, ODI), then Test matches (up to five days). There are three established international formats in cricket. England won the final in London four years ago by the barest of margins and will be expected to beat a New Zealand side who are always a tough proposition. The ICC Men's 2023 Cricket World Cup will start on October 5 with a repeat of the previous final, in 2019, between champions England and New Zealand.
