Eden Hazard downplayed the disturbing scene which saw him hugged by a pitch-invading fan at the final whistle of Chelseaâs 2-1 win at Malmo.
The culpritâs grip was released only when the Belgium forward handed over his shirt and UEFA are likely to investigate.
The fan, one of at least four from the home stands who encroached onto the playing surface, was escorted off by stewards, holding the shirt.
Hazard appeared unnerved and later brushed off the moment.
âItâs not an incident. He just asked for my shirt,â said Hazard, who came on as a second-half substitute in Thursday nightâs Europa League last-32 first leg in Sweden.
Chelsea responded from their embarrassing 6-0 mauling at Manchester City, but were less than convincing and received a stark warning from head coach Maurizio Sarri afterwards.
Goalscorers Olivier Giroud and Ross Barkley had put the Blues 2-0 up.
Chelsea appeared to be coasting at 2-0, through goals from Ross Barkley and Olivier Giroud, but Anders Christiansenâs strike 10 minutes from time means the Bluesâ progression to the last-16 is no formality.
Sarriâs future remains in doubt ahead of a crucial week: Mondayâs FA Cup tie with Manchester United, next Thursdayâs second leg with Malmo and the February 24 Carabao Cup final with City. The Wembley date is followed by the Premier League clash with Tottenham.
The 60-year-old Italian said: âIf we concede a goal like this to a team like Manchester City or United or Tottenham, then you risk conceding three goals in 10 minutes. So we have to do better, I think.
âWe need to have continuity and consistency, I think, in the mental condition to be able to approach every match with the same level of application, determination and attention.
âYou know very well that, if you are in bad mental condition in England, in 10 days you can lose three or four very important matches.
âSo we need consistency. We have to approach every match in the same way. Itâs not easy, but we have to try.â
Sarri was content with the performance, which saw Chelseaâs first away goals in 2019 after losses to Arsenal, Bournemouth and at the Etihad Stadium.
âI am happy because we played with a very good level of confidence,â Sarri added.
âIt wasnât really very easy after the last match. But, today, we were confident because we moved the ball also inside our box.
âWe need to think we have to gain qualification in the next match at Stamford Bridge. We have to play because they are really very compact, very solid.â
As well as the small pitch invasion, UEFA is likely to scrutinise Malmo supportersâ use of flares and the throwing of drinks over the partition between home and away fans.
Malmo were playing for the first time since beating Besiktas to reach the knockout stages due to the domestic off-season during the harsh Swedish winter.
Boss Uwe Rosler was pleased with his sideâs performance.
âWeâve not shown any respect to Chelsea, especially in the beginning of the game,â Rosler said.
âChelsea didnât have a single chance before they scored.
âIâm pleased with the way we approached the game, tactically and mentally. They showed us respect. They brought (NâGolo) Kante and Hazard on. Thereâs a reason for that.â
The late goal has given Malmo a chance of an upset.
Rosler added: âThe odds were against us in the beginning, and are again now. But we rewarded ourselves for the way we played.â
