Former Real Madrid GM Jorge Valdano has angered wing-back Marcelo.
For the left-back, a comment made by Valdano really struck him.
"A few days before the final a former Real Madrid player had said something about me on TV that stuck in my head," Marcelo wrote for the The Players' Tribune, referring to Valdano who was speaking on 'El Transistor' radio programme on Onda Cero on May 6, 2018.
"He'd been asked what he thought about the final, and he said, 'I think Marcelo should buy a poster of Mohamed Salah, put it up on his wall, and pray to it every night'.
"After 12 years and three Champions League trophies, he disrespected me like this on live TV.
"This comment was meant to sink me, but it gave me so much motivation."
