Arsenal's Mesut Ozil says that the intensity of playing for Real Madrid is relentless, insisting that every game as a Los Blancos player is a must-win.
The Germany international made 159 appearances for the Spanish giants following his 2010 arrival from Werder Bremen before Arsene Wenger signed him for Arsenal in 2013.
And while Ozil found relative success with Madrid, leaving the club with a 2011-12 Primera Division winners' medal, he says that the pressure from supporters was never far away.
"Everything is so different. If you play for Real Madrid and you draw against Barcelona, it's the worst," Ozil told Arsenal's YouTube channel. "You have to win every game.
"If you win 10 games in a row and then draw at home against a smaller team... there's [immediate] pressure."
Ozil also revealed how his move to the Spanish capital came about as he followed in the footsteps of his childhood hero - now the Madrid coach - Zinedine Zidane.
"My idol was always Zidane and he played for such a big club like Real Madrid," he added. "They wanted me, especially [Jose] Mourinho. I spoke with him on the phone and he told me his ideas and what he thought about me as a player.
