Lazio striker Floccari made an emphatic impact in their Group J match in Trabzonspor, coming off the bench in the second half with his side trailing 3-1 and scoring two goals in as many minutes late in the game to grab a point for the Italians.
Elsewhere, Eintracht Frankfurt, Ruban Kazan, Sevilla and Fiorentina joined Racing Genk, Swansea City, Ludogorets and Salzburg in getting two wins from two games in their respective groups.
Valencia shrugged off the scars of their opening defeat by Swansea to secure three vital points in Russia with a 2-0 win at Kuban Krasnodar and Lyon were held to a 1-1 home draw by Portuguese side Vitoria Guimaraes.
A second defeat for Valencia could have left them facing the possibility of a shock early exit but Paco Alcacer came off the bench to open the scoring and Sofiane Feghouli added a second late in the second half with a precise free-kick.
PSV Eindhoven, who also suffered a surprise loss in their first match, recovered with a 2-0 win over Ukrainian side Chernomorets Odessa and stoppage-time goals rescued draws for PAOK Salonika and Rapid Vienna.
The darker side of football showed its face in Sofia as 45 fans of Croatian champions Dinamo Zagreb were detained for acts of violence before their team's 3-0 defeat by Bulgarian champions Ludogorets.
