Neil Ryan’s side drew 3-3 in the Italian capital, and Heaven powered home a brilliant header to make it 3-0, appearing to land a little awkwardly but celebrating as he hobbled away.
The goal was assisted by Tom Watson, from a corner, and the Brighton & Hove Albion winger, currently on loan at promotion-chasing Millwall, scored the first two goals as the Three Lions took control.
However, the hosts stormed back to force a draw in an entertaining game.
