In an emotional farewell to Real Madrid on Monday, Casemiro claimed that his upcoming move to Manchester United was not driven by financial considerations.
After nine years with Real, the 30-year-old Brazilian midfielder declared he is joining “the biggest team in the world.”
Casemiro will join United on a four-year deal for up to £70 million, making him one of the highest paid players at the three-time European winners.
“If it was about money I would have left four or five years ago,” he said.
“Those people who think that are wrong, they don’t know me at all.
“The club has always treated me very well. It’s my decision, my path.”
“I spoke to my agent after the Champions League final as I had the feeling that I was coming to the end of my cycle here,” said Casemiro.
“It was the hardest decision of my life but I’m excited about what’s ahead of me. I want to face new challenges, know a different league, a different country and a different culture.
“I’m going to the biggest team in the world, that can compete with the greatness of Real Madrid, although now it doesn’t.”
United, who has dropped its opening two Premier League games, will play Liverpool on Monday at Old Trafford.
Together with Casemiro, Cristiano Ronaldo won four Champions League championships at Real, but this summer, the Portugal star has been heavily linked with a move away from Old Trafford.
“I haven’t spoken to Cristiano, I hope he stays because he’s one of the best players of all time,” Casemiro added.
“Everything I did here, I want to do there too. I want to win the league there.
“I am going through one of the best moments of my career. I feel I’m really fit, mentally I feel great, and I feel like it’s a great moment to take this decision.”
Florentino Perez, president of Real Madrid, shed a few tears during the ceremony at the facility where the Spanish champions train.
“You have been exemplary every single day in all of these years here,” he said. “You have earned the right to decide your future and we must respect it.
“You leave the image of the champion that you are. You are going to a friendly club, the legendary Manchester United, but wherever you are you will always be an ambassador of Real Madrid.
“You will always be one of us. This is and always will be your home.”
