Morgan has been delighted by the progress England have made under Bayliss since the 2015 World Cup saying they have improved a lot faster than anyone thought they would.
Bayliss has been the subject of plenty of criticism following England's Ashes defeat, but it has been clear throughout his tenure that apart from home success, his remit had been largely directed at the 50 and 20-over formats.
This match is Jos Buttler's 100th for England, and he was presented with a commemorative cap by James Anderson before play. "As a coach the one attribute he has is the ability to take the pressure away from any player at a time when you need it and that has helped me massively".

"Originally, England probably played with too much freedom and not enough nous, but now they are so much more experienced as a group and as individuals that they are being far more consistent than they ever have been", said Taylor, who averaged 42 in 27 ODIs.

Ben Stokes is the exception, of course. He has been named in the T20 squad for the tri-series with Australia and New Zealand, as well as the Test series against the latter which takes place in March.
Probable XI: Jason Roy, Alex Hales, Joe Root, Eoin Morgan (c), Jos Buttler (wk), Jonny Bairstow, Moeen Ali, Chris Woakes, Mark Wood, Adil Rashid, Liam Plunkett. "We will miss him but we know he is not going to be part of this series so we can address the balance of this side".

Toss: Eoin Morgan, the England captain, won the toss and opted to bowl against Australia in the first One-Day International at Melbourne Cricket Ground on Sunday (January 14). An internal European Central Bank disciplinary hearing will not take place until Stokes's legal case has concluded, which has allowed Hales to return to global duty.
