The megastars of Real Madrid play MLS team Toronto FC in a friendly game tonight.

Temporary grass has been installed on top of the usual artificial surface for the game, which was a demand from Real before they would agree to play.

They trained on the field yesterday for 50 minutes in an open session offered to fans for $15, and 18,000 people turned up.

Toronto's ground, BMO Field, only holds around 20,000 people.
