Police will deploy "hooligan spotters" in Glasgow today over fears Dutch fans are planning to fly in for Celtic's match against Aberdeen.
Feyenoord supporters are understood to be planning a trip to the city at the weekend to attend the match.
Officers said they have "intelligence" from social media discussions between sections of the Celtic support and Dutch fans.
The Evening Times understands around 120 Feyenoord supporters plan to arrive in the city.
A police insider said: "We know about them and we're ready."
Police will have a specialist policing plan in place throughout the weekend.
A Police Scotland spokesman said: "We are aware of discussion on the internet in relation to a section of travelling supporters."
It comes days after some Feyenoord supporters became embroiled in a racism row during their side's Europa League match against Roma.
The referee was forced to stop the match twice over the incidents during Thursday's game.
Officers arrested more than a dozen Dutch nationals and five Italians before the match.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.

We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers.
