Manchester City have been charged by UEFA after fireworks were let off at the Etihad Stadium during last night's Champions League quarter-final second leg against Paris Saint-Germain.
City won 1-0 on the night to seal a 3-2 aggregate victory and advance to the last four of Europe's elite competition for the first time.
However, the club could now be fined by UEFA because of the charge, which will be dealt with on May 19.
City will find out their semi-final opponents this Friday. Real Madrid joined them in the last four yesterday, while the other two semi-finalists will be determined tonight. Defending champions Barcelona go to Atletico Madrid with a 2-1 lead, while Bayern Munich head to Benfica with a 1-0 advantage.
