Micah Richards has revealed that the Manchester City squad received a "hostile" welcome after arriving in Naples for tomorrow's Champions League match against Napoli.
"Wow just arrived in naples! Hostile isn't the word! Geeezeeee," the 23-year-old wrote on Twitter.
The club have sent letters to all their supporters that will be attending the match to be vigilant during their visit to the Italian city.
Several Bayern Munich fans required hospital treatment for stabs wounds when they played in Naples last month.
Liverpool fans also clashed with Napoli supporters during their Europa League tie last season.
