Are Manchester United Actually Playing Fabio Instead Of Rafael?

Mid-way through the first half between Manchester United and Fulham at Craven Cottage, the ESPN camera panned to a slow-mo of Rafael, as it zoomed in on his boots, they clearly show that they belong to his twin brother Fabio:

Fabael

There are numerous possibilities for the reasons behind this:

-Rafael and Fabio share boots.
-Fabio and Rafael are playing tricks on each other again.
-Fabio is trying to assert his dominance by writing his name on things his brother owns.
-Fabio is actually playing for Manchester United despite being on loan at QPR.
-Rafael and Fabio are playing tricks on everyone similar to the Olsen Twins in ‘The Parent Trap’.

Suspicious? Not really, probably Mammy Da Silva packing their bags and having a mare.
