There were other restrictions, e.g., teams from the same city (e.g., Sevilla and Real Betis) in general did not play at home on the same matchday (UEFA tried to avoid teams from the same city playing at home on the same day), and Russian and Kazakh teams did not play at home on the last matchday due to cold weather.
If two or more teams are equal on points on completion of the group matches, the following criteria are applied to determine the rankings:[1] The matchdays were 19 September, 3 October, 24 October, 7 November, 28 November and 12 December 2013.
