Versatility is key in the modern game, especially for youngsters who are keen to impress, and Borthwick-Jackson ticks the necessary boxes to get Louis van Gaal's attention.
Not renowned for being a ball-player, the teenager's physicality and defensive solidity has helped propel him up the ranks at Carrington.
"He has an unusual stance and running style, which came from being so tall from a young age," Swain added.
"His arms were everywhere, and that looked unusual. However, it just added to his presence and made him hard to breach. He flew into challenges, no matter who he was up against, he is fearless."
His strength and size are keen to his game. A left-footer - which Swain believes appealed to Van Gaal - makes him the perfect partner in the middle, or a more physical presence at full-back.
