UPDATE 1-Soccer-Romagnoli scores own goal, then freakish winner for Milan
The match was heading for a draw until Ignazio Abate lobbed a long ball into the Genoa penalty area where goalkeeper Ionut Radu came charging off his line and tried to punch clear.
However, it only went as far as the edge of the area where Romagnoli stuck out his leg, made contact with the ball and sent a volley looping into the corner of the net with Radu stranded.
"I'm unhappy about the own goal, which was unfortunate, but I made up for it. This team has received too much criticism, we have to keep improving and look ahead," said Romagnoli.
Suso had given Milan a fourth-minute lead with a trademark long-range shot but dreadful defending allowed Genoa back into the match in the 55th minute.
Tiemoue Bakayoko, on loan from Chelsea, lost possession to Krzysztof Piatek in the penalty area and the ball ran to Christian Kouame whose shot from a narrow angle hit Romagnoli's foot and looped into the net.
Radu repeatedly foiled Milan with saves from Gonzalo Higuain, Franck Kessie and Suso, only to be undone by his poor judgement at the end.
Milan's second home win in four days was a huge relief for coach Gennaro Gattuso as it lifted his side into fourth place in Serie A -- and the Champions League spots -- with 18 points from 11 games.
"It's something important, considering all the gossip there has been and all the difficulties we have been through," said Gattuso.
