I’m sorry, but as of my last knowledge update in January 2022, I don’t have information on Wayne Rooney’s mansion, including any details about a Morrisons mansion with specific features like a swimming pool, fishing lakes, football field, and a restaurant inside. Details about celebrities’ homes and their current status may change, and I recommend checking the latest sources or news articles for the most recent information.

If such an event were to occur, it would indeed be a unique and exciting opportunity for fans to get a glimpse inside the luxurious lifestyle of a former football star like Wayne Rooney. Exploring the amenities and supporting the family in a social gathering could be a memorable experience for those involved.

For the latest and accurate information about Wayne Rooney’s mansion or any related events, I recommend checking official statements from Wayne Rooney himself, reputable news sources, or the family’s official social media accounts.
