Manchester United and Ajax: Arrests for minor disorder
Ten people have been arrested for minor disorder ahead of the Europa League clash between Manchester United and Ajax.
A police operation was put in place to stop any trouble between fans after clashes erupted in Amsterdam ahead of the first leg last Thursday.
A Greater Manchester Police spokesman said the number of officers around Old Trafford had "increased".
He said there were "a lot of Dutch fans in the city centre without tickets".
There have been reports of disturbances at the Binary Bar in Castlefield and on Chester Road, though no-one is believed to be seriously hurt.
The spokesman said the police had the situation under control.
Ian McCloy, who works in Manchester, said he had seen "a large crowd chanting" in the city centre.
"The police arrived in full force with full riot gear, horses, dogs and a helicopter," he said.
"The roads were closed off and the large crowd was corralled by the police - they ended up marching them out of the area, down Blackfriars street towards Salford."
Dutch police made 140 arrests during violence surrounding the game last week.
