Real Madrid defender, Marcelo believes the small details will be the defining in the final of the UCL later today.
In a repeat of the 2014 UCL final, Real Madrid will be hoping to repeat the 4-1 scoreline and see off city rivals.
And Marcelo is sure his side will leave no stone unturned as he knows the finer points could prove decisive.
“We’re feeling as good as we could,” he said. “We’re ready, prepared and I think we’ll fair quite well.
“I think in a final what decides the game is the small details and we’re thinking of all those. Everyone wants to win, you need to work and run a lot and I think the small details are what’s going to make a difference.”
Marcelo came on as a substitute and scored Madrid’s third goal in the final victory two years ago and he still revels in the memory of that occasion.
“It’s impossible not to think of that game. It was very special,” the 28-year-old added. “I personally believe that it’s in the past, it’s over now and it’s another final.
“[On Saturday] we have a chance to live a great day for us, but in order to do that we need to fight because it’s the Champions League final and it’s always very difficult to win.”
Zidane declared Ronaldo, who needs two more goals to break his own record of 17 in one Champions League campaign, to be “100 per cent fit” for the match in Milan.
