A banner protesting against Everton’s 10-point penalty for breaching financial rules was flown over Etihad Stadium during Manchester City’s Premier League match with Liverpool.
The banner – which read “Premier League = corrupt” – was organised by Everton fans’ group The 1878s.
It flew over during the second half of Saturday’s lunchtime fixture.
Earlier, a banner requesting the release of a prominent activist in the United Arab Emirates was flown over.
The match between the Premier League’s top two teams finished 1-1.
Everton have been given the biggest sanction in Premier League history, dropping them from 14th in the table to 19th.
English top-flight clubs are permitted to lose £105m over three years, and an independent commission found Everton’s losses to 2021-22 amounted to £124.5m.
The club intend to appeal, and Everton boss Sean Dyche said on Friday they felt “aggrieved” by the “disproportionate” punishment.
Supporters are planning further protests at their Premier League fixture against Manchester United at Goodison Park on Sunday (16:30 GMT).
In February, City were charged with more than 100 breaches of the league’s financial rules following a four-year investigation. That case is ongoing, and City have denied any wrongdoing.
City boss Pep Guardiola said the 115 charges they face represented a “completely different” case to Everton’s and could not be compared.
