Paulo Dybala’s pinpoint cross found Lukaku, who scored with a diving header from close range five minutes into the game.
Midfielder Zalewski was sent off in the 64th minute after receiving a second yellow card. Fiorentina equalized two minutes later through a cross headed in by Lucas Martinez Quarta.
Lukaku was awarded a direct red card three minutes before halftime after he collided with Christian Kouame of Fiorentina in a slide tackle.
After the Belgian striker’s follow-through tore Kouame’s sock to shreds, Mourinho’s squad played the rest of the match with nine me𝚗.
Despite losing Dybala and Sardar Azmoun to injuries and seeing two red cards each from Lukaku and Zalewski, Roma were able to hold on for a point on a hectic night.
At the final whistle, Mourinho voiced his disapproval of the decision and several others he had been displeased with during the game.
Since Mourinho and the Roma players declined to speak to anyone following the match, the Portuguese boss departed without addressing the media.
Instead, Mourinho passed the media area alone, saluted Vincenzo Italiano, the coach of Fiorentina, and then left.
This puts Roma on 25 points, good for fourth place in Serie A; they are behind third-place AC Milan by four points and league leaders Inter Milan by thirteen.
Nikola Milenkovic became the third player for Fiorentina to receive a red card in the match, bringing their total number of players sent off in stoppage time to eleven. Despite this, boss Italiano was pleased with his team’s effort in the second half.
‘They were only down to nine for a few minutes,’ he told DAZN. When we realized we had taken the wrong approach in the first half and allowed Roma to capitalize, we wasted no time getting back on track in the second half.
