No further clues were given as to the starting XI for the first of five ODI matches, although Morgan did hint that all three openers - Jonny Bairstow, Jason Roy and Alex Hales - could feature.
Finch duly went to his third ODI century against England on this ground, and second in as many innings after the opening match of the 2015 World Cup, by swinging Rashid into the crowd with plenty of bottom hand.
"Everyone does everything they can to play for Australia or England". I've played a lot against those guys in the Champions Trophy, in series in England and here, too.
Australia captain Steve Smith is sure this month's one-day worldwide series against England can hold its own against the allure of the Big Bash.
The ECB, however, finds itself in a hard position, for to remove Bayliss now would be to risk so much of the good work that he has done in the white-ball formats. After racking up a staggering amount of runs during the Tests, he will again lead the side in the ODIs and the question of how to get him out will continue to haunt the English attack.
Both teams are vastly different to their Test line-ups, with a number of limited-overs specialists coming in as they start to prepare for next year's World Cup. England then face a Test series at home to Pakistan and India next summer which might not be a walk in the park either. Australia 199 for 4 after 36 overs.
Asked if they might enjoy better results than their Test colleagues, he said: "I hope not. They're good one-day bowlers and a good one-day outfit so it's a good challenge".
For what it is worth too, I stand by my initial belief that England should not have appointed Bayliss in the first place and that they made a decision to recruit the wrong Australian. "I don't know why this is news".
England skipper Eoin Morgan believes that the pace at which cricket is changing, particularly in shorter formats, will see countries employ different coaches for different formats.
Bayliss's laid-back approach has fitted in well with a group of young, exciting players who have shone in an environment that has promoted aggression and flair.
Eoin Morgan has leapt to the defence of England head-coach Trevor Bayliss, praising him for lifting the pressure off the squad.
The series against Australia will be interesting if only to see how England respond to the Ashes defeat.
Can England maintain their white-ball surge?
