Heaven credited head coach Ruben Amorim with playing a pivotal role in convincing him that United was the right environment to nurture his potential.
"He just said that our play style will suit me, because they play three at a back and I play on the left of the three, so that allows me to run with the ball," Heaven remembered.
"That's one of my strengths. And defending out wide is one of my strengths as well."
