A West Ham fan was taken to hospital after a group of supporters were attacked by what witnesses say were a set of Eintracht Frankfurt ultras, German police have confirmed.

In the early hours of Wednesday morning, two vans stopped outside a pub in the Hesse city where a group of Hammers fans were drinking.

Witnesses say around 15-20 people donning face coverings and appearing to be fans of Europa League opponents Eintracht got out of the vans, before entering the pub and attacking the visiting supporters.
