it is about mbappe actually. if he really wants to be next galacticos and continue legacy of cristiano ronaldo under zidane he will prefer real madrid. but if he wants develop as young player under best manager for youngsters pep he will select city. i think if madrid could succeed sell morata to milan for 70 as they already sold james they will sign top attacking prospect. mbappe is once generation player without any doubts and his signing to city may be reason for our dominance in next decade. but it is not critical as left back singning because we already we have young talented striker gabriel jesus.
