During his seven-and-a-half years as England white-ball captain, Eoin Morgan oversaw a stunning transformation as he led them to glory in the 2019 50-over World Cup and the final of the 2016 T20 World Cup.
Now that he is retired from international cricket, having decided to step away five months before England won last year's T20 World Cup, Morgan is watching on with interest as Ben Stokes and Brendon McCullum have sparked a similar revolution in Test cricket.
Since taking charge of a side that had won just one of their last 17 Tests, Stokes and McCullum have encouraged a more positive and aggressive approach that has seen them win nine in ten against New Zealand, India, South Africa and Pakistan.
