Images have been released of 12 men police want to question over violence which broke out in Manchester last October following a World Cup match.
Disorder broke out during the England v Wales match
The images were taken of disorder in the city centre during the England v Wales match in October last year.
Greater Manchester Police (GMP) hope the images may jog fans' memories as they gather for the England v Austria qualifier in Manchester on Saturday.
GMP believe the men are from all over the country.
"It is likely that all 12 men will be avid football fans and someone may see them if they attend this match or if they are in Manchester to watch it," said Det Sgt Simon Raistrick from the Force Intelligence Bureau.
Police say the men are from all over the country
"However, we believe they do not live in the Manchester area and will have travelled in specifically for the match.
"I would therefore urge people from all over the country to look at these pictures and call us if they have any information about the identity of the men."
Officers have already arrested and charged 64 people over the violence.
