The 20-year-old has joined the Red Devils after the end of his contract at Championship club Swansea City. United have agreed a compensation package, with the Welsh club entitled to remuneration because of their role in developing the player. He didn't make his first-team debut with the Championship club but had the first taste of senior football last season on loan at Cymru Premier outfit Connah's Quay Nomads. United made a slow start to the summer transfer window, but transfer activity has picked up significantly in recent weeks. The Red Devils could also add an elite winger to the squad if Marcus Rashford ends up leaving the club this summer.
