The Britannia has not been a happy hunting ground for Mancini but City did beat Tony Pulis side in the 2011 FA Cup final when Yaya Toure scored the only goal to lift the club's first major trophy since 1976.
Mancini said: "I have good memories, it was a fantastic moment. We wanted to win that final to start to win trophies.
"To win a trophy after 35 years was very important for us because we worked hard and also for the club and our supporters. It changed our mentality."
