Porto have been fined 20,000 euros after their fans were found guilty of aiming racist abuse at Manchester City`s Italian forward Mario Balotelli, the English Premier League club said on Tuesday.
City complained about Balotelli`s treatment after their 2-1 win away to the Portuguese side in the Europa League on February 16 in the round of 32.
"The UEFA Control and Disciplinary Body has imposed a fine of 20,000 euros on FC Porto for racist conduct of their supporters..." said a UEFA statement published on City`s website (www.mcfc.co.uk).
Porto, who have three days to appeal, said at the time they were surprised about the complaint and nothing abnormal had happened during the game.
A spokesman said chants from Porto and City fans in support of their respective players Hulk and Sergio `Kun` Aguero could have been mistaken for other sounds.
The Portuguese club said they had no previous record of racism and were proud to field a multi-racial team.
However, Porto fans said they had briefly heard monkey chants from a part of the stadium after a foul by Balotelli.
