Josip Ilicic put on a masterclass for Atalanta to overturn Roma 4-1, providing assists for Duvan Zapata and Robin Gosens before slaloming past defenders.
Edin Dzeko had struck early in Bergamo, making the most of a Henrikh Mkhitaryan assist, and Leonardo Spinazzola was denied only by the frame of the goal.
However, when Ilicic came off the bench, the game changed, as he set up the Duvan Zapata thunderbolt off the underside of the bar and a towering Robin Gosens header.
Luis Muriel was also a supersub, intercepting the Jordan Veretout pass to score with his first touch.
Ilicic capped off a wonderful display with a brilliant solo goal, slaloming past several challenges to surprise Antonio Mirante.
