More sophisticated case of "me and I"!
Which of the following is correct? "I agree that it will be just me and you managing the projects." or "I agree that it will be just I and you managing the projects."
Solution 1:
"Me". You can judge this by considering the following different ways to say what you mean: "it will be just us" and "it will be just we". Now if "we" sounds wrong to you, then "I and you" should also sound wrong and for the same reason: the pronouns "we" and "I" are in subject case. So if you prefer "us", then also prefer "me and you".
