According to the Daily Mirror, however, Rafael only managed to get to sleep at 5am following the birth of his child.
Manager David Moyes granted Rafael permission to attend the birth of his baby before the match.
The 23-year-old has 5 goals in 95 appearances for United and has two international caps for the Seleção.
