The mother of Manchester United's Da Silva twins has concerns about them splitting up next season.
Fabio will leave Rafael in England to join Benfica on-loan.
Laurinda Silva told O Jogo: "I'm a little worried about the separation of the two, because its never happened before. But we talked about it and, as Lisbon is close, it will give Rafael the chance to visit when he has a break or Fabio can go to England too."
