UEFA have ordered Lazio to play their next two European home matches behind closed doors following the behaviour of their fans.

Supporters have been accused of racist chanting and throwing fireworks during their team's 2-0 Europa League win over Borussia Monchengladbach at the Stadio Olimpico on Thursday.

Lazio, who have also been fined £34,000, will now play the first leg of their last-16 tie against Stuttgart inside an empty stadium.

The Italian club has already been punished twice this season for similar incidents against Tottenham Hotspur and Maribor.
