One man was treated for a head injury and GMP confirmed the arrests in a statement on its Twitter feed.
Video footage of the incident posted on the internet showed men throwing tables, chairs, bicycles and other objects at each other and trying to smash down a restaurant's glass partitions.
It is unclear what sparked the violence, although reports in Spain suggested fans of Polish club Slask Wroclaw sparked the trouble following violence when Slask and Sevilla met in the Europa League in 2013.
