Robbie Keane's home debut marred as fans disguise themselves to fight rivals

On the pitch, the match did not disappoint with the Hungarian giants running out 4-3 winners to book their place in next month's play-off round.

However, it was a different story in the stands as carnage broke out between the two sets of fans on what was Robbie Keane's home debut as Ferencvaros boss.

In a stunning turn of events, Ferencvaros fans implemented a bizarre way of getting within striking distance of their Dutch counterparts.

Rather than break through the barriers separating fans, Ferencvaros hooligans instead disguised themselves as stewards by dressing in high-visibility jackets.

What followed was a dress rehearsal of this weekend's WWE Royal Rumble as both sets of fans weighed into each other as missiles rained down from the stands.

It's not the first time supporters of either club have been involved in violent scenes.

Ferencvaros fans have long been considered the most violent in Hungary with UEFA having sanctioned the club on multiple occasions in the past.

Hooligans connected to the club stabbed four Millwall fans when the two clubs met in the UEFA Cup in the 2004/05 season.

Meanwhile, AZ Alkmaar were fined £68,768 after thugs entered the stand housing the families of West Ham players at the AFAS Stadion, during the Irons' UEFA Conference League semi-final in 2023.
