UEFA has fined Legia Warsaw 30,000 euros (£25,700) and ordered a partial stadium closure for their next European home game because of racist behaviour from supporters during a Champions League second-round qualifying tie with The New Saints.
The sanction, which relates to incidents during the Polish club's matches with the Welsh outfit on July 17 and 24, will be imposed during Legia's play-off second leg at home to Steaua Bucharest on August 27.
Legia won the tie with TNS 4-1 on aggregate and went on to defeat Norwegian side Molde in the next round to book a play-off meeting with Romanian club Steaua.
For the second leg on August 27, Legia have been ordered to close the north stand of their Stadion Wojska Polskiego.
A statement on UEFA's official website confirmed its control and disciplinary body had charged the Polish club under Article 14 of the UEFA disciplinary regulations on racism, other discriminatory conduct and propaganda, in relation to incidents in both legs against TNS.
