The club is set to release details of celebration events at the Premier League clash with Andre Villas Boas' Champions League chasing side on May 12.
City's chief executive Tony Scholes, pictured, explained: "We did consider having a big match, but we play in the best league in the world so already have at least 19 big home matches.
"Some of them are against some of the biggest clubs in the world, so to put on a game beyond that would be extremely difficult.
"Unless it was against a Real Madrid or Barcelona then we didn't feel it would capture the imagination sufficiently. So we decided to choose one of our Premier League games as our anniversary celebration day."
