gracias

Like on the gigantic banner outside, the LED screens flashed 'Gracias Rafa' during his emotional farewell speech.

The caricature is sandwiched between two words: "Gracias Rafa."

"Gracias is the first word which comes to mind when you reflect on everything we have witnessed over the past 20 years, watching Rafa play," Feliciano Lopez, Nadal's former Davis Cup team-mate and a close friend for more than 20 years, told BBC Sport.

"I think 'Gracias Rafa' is something that every tennis fan in the world is thinking right now."

Once the anthem stopped, he was able to raise his arm into the air and mouthed "Gracias" to the supporters chanting his name.
