The 30-year-old Spaniard noted that the births of his three kids have so far all coincided with major title wins at both Barcelona and Chelsea.
And Fàbregas has appeared to send a message to his partner Daniella Semaan that they should have another baby as good luck in 2018.
Daniella, though, believes there may be another way to success.
