Morgan & Co started their campaign on a solid note with a massive 104-run victory over South Africa in the tournament opener. "They have the potential to be a great one-day team". Another easy win against West Indies followed.
Roy struck five sixes and nine fours before being given out caught behind even though he didn't touch the ball.
A similar result followed against Australia in their next match. "That's how I started playing my cricket back in Australia". Chasing a target below 300, the team just did not look equipped enough to face the swinging deliveries from Jason Behrendorff first up.
Roy requested a review but England had already squandered their lone review of the innings with an unsuccessful attempt to overturn fellow opener Jonny Bairstow´s lbw dismissal for 34.
Morgan consulted with leadership experts at the beginning of the four-year cycle, including England's own team psychologist David Young.
A win against India by 31 runs was a massive boost for England.
England's win over New Zealand followed victory over India as the hosts won their final two pool games to secure qualification for the semi-finals. However, that was not to be as Chris Woakes and Jofra Archer dished out nearly unplayable deliveries to the Aussies, before Jason Roy made easy work of the 227-run total.
"I think it shows the passion Jason has got for the game, and it is such a big game as well, when he was on the verge of scoring a hundred", he said.
"Last 12 months, if you told us we were going to be in a semi-final and come second in the group stage we'd have been really happy".
"Sunday is not a day to shy away from, it's a day to look forward to, much like today", he said.
"We managed to win games without playing the ideal game the whole way through". "It will be a matter of the same again, trying to produce everything that we can performance-wise".
Morgan and boys will now be up against New Zealand in the Final.
"That has worked out extremely well for us and given the support that we've had throughout, the ECB (England and Wales Cricket Board), the backroom staff, as players we have taken that as far as we can so far".
Indian supporters pose for a photograph in the crowd during the 2019 Cricket World Cup first semi-final between India and New Zealand at Old Trafford in Manchester, north-west England, on 9 July 2019.
Kumar Dharmasena and Marais Erasmus will umpire the World Cup final at Lord's on Sunday, it has been confirmed by the ICC.
By getting to the final for the fourth time, England have ensured the match will be screened on free-to-air TV in Britain - the first time this has happened since the 2005 Ashes series on home soil - and Morgan feels their achievement has made the sport "very cool".
