The 29-year-old has been praised following his hat-trick in United’s 3-1 victory over Wolfsburg on Tuesday.
“Fabio has said himself, performance is the only thing that matters,” said Ferguson.
“If Michael is going to get to the World Cup it will be through his performance and I think Tuesday helps him.
“There is a view that he will not have played enough games. But he will play a sufficient number to be considered.
“That is the best chance he has got. That is all he can hope for.”
