Upon arrival, Barcelona paid for a huge electronic banner that clearly aims a dig at Real Madrid.
The message on it, with a picture of Barca president Joan Laporta, reads: "We are Barca, but don't worry, Merengues – what happens in Vegas, stays in Vegas."
Real Madrid are also known as Los Merengues - a reference to the French monicker 'Meringues' due to their all-white kit. So Laporta knows exactly what he's doing.
Real Madrid will play Barca in the early hours of Sunday morning, then we'll all see what really happens in Vagas.
