The two clubs will meet in the Champions League quarterfinals.
"I have no hard feelings towards [Real] Madrid or anything of the sort. I have only good words for the club. I'm a person who always thinks positively and very few players in the world can say they've played for them," Altintop told Marca.
"Mourinho is a great coach and person who knows a lot about football and has everything under control. He handles things in the dressing room effortlessly. He knows when to be close with a player and when to walk away.
"[Ronaldo] is a decisive player and one of the best in the world, but Madrid are not just about Cristiano, they are a great team. If we thought we could progress only by stopping Cristiano, we'd be wrong."
