Arsenal also hosted the Emirates Cup in the Emirates Stadium for the first time since 2011 after the 2012 edition was cancelled due to the London 2012 Summer Olympics causing infrastructure problems in London. It was confirmed on 15 May 2013 that Turkish Süper Lig side, Galatasaray and Serie A side Napoli were to Arsenal's opponents although this did not receive a good reception from Arsenal fans after the 2000 UEFA Cup Final riots where Arsenal and Galatasaray fans clashed in Copenhagen, Denmark before the Uefa Cup Final. The third side was Porto who played their two games against Arsenal's two opponents. Arsenal's final pre-season friendly was against fellow Premier League side Manchester City in Helsinki seven days before the season is set to begin. This meant a total of seven pre-season games for the Gunners. It had also reported in 2012 that, after Arsenal postponed a planned friendly with Nigeria in August 2012, the Gunners would play Nigeria in Abuja Stadium in 2013 however this did not materialise.
