The 2019 World Cup hosts have just a few days to recover from a stunning one-day global defeat before they face title-holders Australia in the first of a five-match series at The Oval on Wednesday.
MacLeod made 140 not out as Scotland surpassed their previous record total at this level of 341 for nine against fellow non-Test nation Canada at Christchurch four years ago. Jonny Bairsto hit a brilliant 105 to become the first Englishman to post three successive ODI centuries. But Safyaan Sharif sealed Scotland's victory with seven balls to spare dismissing last man Mark Wood to spark a pitch invasion by jubilant home fans.
"They don't have to do it but it's something we want to bring in at the start of a series, not before every game", said Paine, of the handshake idea.
"At the end, England didn't really finish the job", he added.
"It's a completely different challenge and a completely different team that we will be playing", said Bairstow. We know we're going to have to be at our absolute best.
Morgan, however, accepted they had been well below the standard needed to win in what was their first 50-over match of the British season.
"We set our stall out to be number one in the world and that's where we are, whether we were number one in this game or not, Scotland would still be delighted to win, it's not just because we are number one".
"We didn't do enough to win, if we had won it would have been a bonus given the position we got ourselves in".
First Scotland impressed the cricketing world with their performance in Zimbabwe at the qualifiers, where they missed out of a successful result after a controversial Duckworth-Lewis loss to the West Indies in March, and on Sunday, once again they proved they have the potential to produce competitive cricket.
When International Cricket Council (ICC) announced its decision to shrink ICC Cricket World Cup from a 14-team tournament to 10-team, they had faced heavy criticism for the same.
"From what I have read, we are not expected to trouble them too much".
On a personal front, the series presents the 24-year-old Agar an opportunity to nail down his spot as the lead spinner of the side.
"If the ICC and other global teams look at this game they will see we are not an add on".
