The Union of European Football Associations (UEFA) decided on Friday to fine Arsenal and Bayern Munich, as well as suspend Tottenham Hotspur's Delle Alli for three matches.
UEFA stated that a fine of 5,000 euros (about $5,400) has been imposed on Arsenal for the field invasion by their fans in the second leg of the Champions League's last 16, played in London on March 7 against Bayern Munich.
The German club was also fined 3,000 euros ($3240) because its fans threw objects onto the field during the same match, which ended 5-1 triumph for Bayern.
In addition, the control, ethics and discipline committee of UEFA also sanctioned Tottenham's midfielder Alli with a three-game suspension, after he was sent off with a red card in the second leg of Europa League's last 32 on February 23 against Belgian side Gent.
The 21-year-old collided roughly with Gent player Brecht Dejaegere 40 minutes into the match, which ended with a 2-2 draw and the elimination of Tottenham from the Europa League.
