Valdano, who has worked with some of the greatest forwards in history, compared Mbappe and Vinicius to Brazilian legends Ronaldo Nazario and Romario. He emphasised that certain types of attacking players excel when focused purely on scoring, rather than being expected to contribute extensively to build-up play.
"It is also said that Vinicius and Mbappe do not run enough, but it is impossible for these players to run with endurance efforts," he said. "I trained Romario and I had Ronaldo at Madrid, and making them run around the field was a Chinese torture. They couldn't, they couldn't. What's more, if you played a possession game they would completely ignore it. Now, you put a goal against them in training and they were the best in the world. What you have to do is exploit what they were bought for."
Valdano went on to dismiss that Mbappe and Vinicius may not have the strongest personal relationship, asserting that personal friendships are irrelevant to how players link up during matches.
"The accusation that they are not sufficient friends because they do not seek each other out does not fit," he said. "I am not going there. I do not know what degree of complicity they will have off the pitch, but the fact is that complicity is not obligatory in the locker room. I have known very difficult relationships between players, but on the pitch they understood each other because there was a footballing harmony."
