English fans descending on Porto for the Champions League final were involved in violent clashes on Thursday night.
Video footage shows a number of different skirmishes by the Douro river and supporters are said to have locked horns with the local police after the bars closed at 10.30pm.
Local television in Porto showed footage of various incidents with Chelsea and Manchester City fans arriving ahead of Saturday night’s huge game.
One clip showed a chaotic scene with a number of people running across a road, horns blaring, whistles and yells disturbing the night.
According to reports, Chelsea and City fans clashed with Porto police and each-other in altercations that could lead to heightened security being deployed on the streets.
The latest violence follows similarly shocking incidents on Wednesday night. Manchester United and City fans violently clashed and had to be broken up by baton-wielding military police.
The City supporters took extra delight in seeing United lose the Europa League final on penalties on Wednesday night.
Their jubilation in an Albufeira resort rubbed salt in the wounds for United fans and trouble flared up in popular district bar Oura, according to Portuguese outlet, Expresso.
An eyewitness told the Sun: ‘That set off pushing and shoving followed by fighting in the street.
‘Military police had to wade in with batons to break it up.’
There were no serious injuries sustained in the skirmishes and as yet no reports of anyone being arrested or charged.
City are preparing to face familiar Premier League foes Chelsea in the Champions League showpiece in the Estadio do Dragao on Saturday.
A total of 16,500 fans are allowed to watch the game in the stadium, 33 per cent of the 50,000 capacity, but many more have travelled either in the hope of finding a ticket or simply to be in close proximity to the action while on holiday.
