Swansea City striker Oli McBurnie is backing former teammate Daniel James for success with Manchester United.

Under Graham Potter's stewardship, the 23-year-old thrived in an attacking line-up with James last term, and has no doubt his friend has the ability and character required to develop into a major star at Old Trafford.

"DJ actually rang me the other day when I was sat on a plane and said: 'I can't believe it, Oli, I couldn't get a game [on loan] at Shrewsbury last season and now I'm at Man United. I can't believe the mad way football works'," McBurnie told ManUtd.com.

“He thoroughly deserves everything he gets. I can't wait to see him do it on the biggest stage and show what he can do. We've been room-mates for the last two years. It's funny as we were room-mates in the Under-23s and then I went up to the first team in the first season and, when he followed me, we started going away and became room-mates again.

"He's a great kid, like a little big kid, but so professional and so mature for his age in terms of being a footballer. He knows exactly what he wants and how to get there. The way he's developed and improved over the last six months has been unbelievable. You don't have teams like Manchester United after you if you're not a top, top player.

“Everyone knows about his speed - he's easily the quickest player I've ever played with - but all the other parts of his game have improved so much in the last six months, since he's been introduced to first-team football. He's been playing against experienced full-backs in the Championship and making them look like little kids."
