The left-handed Dubliner emerged on the international scene with Ireland before earning a call-up to England’s limited-overs squads in 2009.
Within 12 months, he had broken into the Test team, having impressed with a series of wonderfully-paced innings that highlighted his ability to combine often audacious strokeplay with intelligent rotation of the strike and to find boundaries at vital times.
In addition to his efforts with Ireland, Morgan had proven himself as a key part of Middlesex’s line-up - particularly in one-day cricket - prior to his England debut, which came against West Indies at Bristol.
Employing cute deflections, sweeps and his trademark change-up shot - a dummy of a reverse-sweep which he then hits down on behind square on the leg side - to good effect, Morgan exhibited his potential against Australia in the NatWest Series.
Yet it was during England’s subsequent Champions Trophy campaign in South Africa that he truly made his mark.
A match-winning unbeaten 62 against Sri Lanka was followed, two days later, by a breathtaking 34-ball 67 at Centurion that set up a 22-run victory over the host nation and alerted the world to Morgan’s capabilities.
When England returned to South Africa later in the year, he once again came to the fore, thumping 85 not out from 45 deliveries in only his second Twenty20 international appearance before helping the tourists to a 2-1 one-day series triumph.
Morgan played a key role in England's surge to World Twenty20 glory in 2010, and showed enough promise in the limited-overs game to be named in the squad for the first Test of the summer against Bangladesh.
He failed to pass 50 in two matches against the Tigers, but provided further evidence of his enormous talent with a sparkling 130 in the first Test versus Pakistan.
Morgan continued to shine in the one-day arena - making match-winning unbeaten centuries against Bangladesh, Australia and Pakistan during 2010.
It was no surprise when the talented left-hander was named in England's Test squad to tour Australia that winter, although he did not play in the Ashes.
Morgan's winter was marred by a broken finger, sustained in the Commonwealth Bank Series against Australia, that saw him withdrawn from the World Cup squad. However, the digit healed quickly and he replaced the injured Kevin Pietersen after four group games.
Morgan compiled his second Test century - against India at Edgbaston - in August 2011 and, having already been named as England’s T20 vice-captain, then led his adopted country for the first time in the one-off one-day international against Ireland in Dublin.
Morgan required shoulder surgery during the NatWest Series with India, ruling him out for the rest of the year, but recovered to be named in the Test squad to face Pakistan.
However, an indifferent run of form in the United Arab Emirates saw him omitted from the Test party to face Sri Lanka.
Morgan continued to sparkle in ODIs that summer, particularly in a 4-0 mauling of Australia, and earned a place in the Test squad to tour India as a result.
He did not play in the India Tests but on the latter part of that tour and in 2013 led England’s limited-overs sides several times while the regular captains were rested, memorably making 124 not out in victory over Ireland. He was in the ranks as England were runners-up in the Champions Trophy.
A sixth ODI century followed versus Australia that winter and, after leading Middlesex in limited-overs games during 2014, he succeeded Alastair Cook as England ODI skipper at the end of the year ahead of the World Cup.
