When in Tinseltown, you never quite know when you're going to bump into someone famous.
And so it proved for Juan Mata when Hollywood A-lister Julia Roberts dropped in to watch Manchester United's training session on Tuesday.
The actress, star of Pretty Woman, Notting Hill and Erin Brockovich, clearly has a soft spot for United and visited Old Trafford last season.
So with Jose Mourinho's team stationed in Los Angeles on the first leg of their pre-season tour of the United States, Roberts popped in to watch them train at UCLA's Drake Stadium.
