Our brilliant Brazilian has already confirmed he is departing Old Trafford in the summer, after four years of sterling service.
Before he goes, there is still much work to be done on the pitch, as we chase a place in next season's UEFA Champions League, but we also have an opportunity to speak with the midfielder in the coming days.
Due to the fact that Case enjoys such a special relationship with our fans, we are offering you the chance to pick the topics for the Q&A with the much-decorated South American.
So, if you have a burning question you would like to ask him, this is a unique opportunity!
