A former Real Madrid and Barcelona star has been slammed for promoting the chemtrail conspiracy theory.
Alfonso Pérez took to social media on Saturday (8 Nov), sharing two photos of contrails criss-crossing the sky.
He asked: “Can someone tell me what they’re trying to achieve with this?”
The former striker was swiftly community-noted, with the clarification: “Trails in the sky form when the hot, moist water vapour from a plane’s exhaust mixes with the cold, low-pressure air in the atmosphere, causing the water vapour to condense and create white lines of condensed water or ice.”
The 53-year-old from Getafe, near Madrid, has not posted since.

Just days earlier, Alfonso had appeared on a podcast, using the opportunity to slam Spanish PM Pedro Sánchez of the Socialist Workers’ Party.
“He should take a step aside,” he said, before going on to praise figures from the conservative People’s Party and far-right Vox.
Alfonso joined Madrid’s senior team in 1990 before moving to Real Betis, in Seville, in 1995.
He signed for Barcelona in 2000, where he remained until 2002, with a short loan spell at Olympique de Marseille that year.
He spent the next three years switching between Barça and Betis before hanging up his boots in 2005.
The striker scored 11 goals in 38 appearances for Spain between 1992 and 2000, as reported by Need To Know.

Named Best Spanish Player by Don Balón in 1998, he won the Copa del Rey twice, as well as La Liga and the Supercopa de España once each.
He was also part of the Spain U23 squad that triumphed at the 1992 Summer Olympics.
The chemtrail conspiracy theory claims that the white trails left behind by aircraft are not just water vapour, but chemicals deliberately sprayed into the atmosphere for secret purposes – such as weather control, population manipulation, or spreading disease.
Responding to his latest question online, one user named Miguel wrote: “To travel from point A to point B through the air on a passenger plane.”
Another, Juanma, joked: “I don’t know, but I’d start putting on a little tin-foil hat, just in case.”
