Chelsea ace Eden Hazard insists there was no problem with a pitch invader at the end of their Europa League win at Mamo.
The fan, one of at least four from the home stands who encroached onto the playing surface, was escorted off by stewards, only after Hazard handed him his shirt.
"It's not an incident. He just asked for my shirt," said Hazard.
As well as the small pitch invasion, UEFA is likely to scrutinise Malmo supporters' 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.
