Mangala has also suggested that he would prefer a switch to Chelsea because of their location in London.
City have also maintained their interest in Porto midfielder Fernando after the club failed in a double move for the 26-year-old and Mangala during the January transfer window.
"Our business was done mostly early in the window [last summer]. We had a great pre-season and season. Expect the same today but even earlier," Al-Mubarak told the club’s official website.
"Today I can tell you that we know exactly what needs to be done.
"We know exactly the players that need to go and the players that need to come in; the areas that need to be strengthened and the players we need to bring in to expect an efficient and swift execution plan.
"We will have the players to compete in four championships."
