Sergio Ramos has declared his belief that Real Madrid have made the wrong decision in choosing to sell Mesut Özil to Arsenal.
The German international became Real Madrid's most expensive sale of all-time after the club agreed a 50 million euro fee with the Gunners.
"If it were up to me, he would be one of the last players to leave Madrid," said Ramos.
"But he has made that decision and so have the club. It's a personal choice and he decides his future. Everyone chooses what's best for them and he's free to do what he wants. I'm not annoyed that he has left, but I am sad about it.
"He was certainly a friend and teammate like no-one else. He is a brilliant footballer, a unique player, and there was always a very good understanding between me and him. It's a shame."
On Madrid signing Gareth Bale, he said: "As captain I'd like to welcome him, we are delighted to have pulled off such an important signing. He will contribute a lot."
On Friday Spain face Finland, who held Vicente Del Bosque's side to a surprise 1-1 draw last March.
"They gave us a big shock, they came to defend from the first minute and didn't create any chances but they equalised with a counter attack.
"Games like that teach you a lot, you have to remain concentrated for the 90 minutes. It's positive to learn from our mistakes. When you spend so many years winning the other teams give you a lot of respect and there's nothing we can do about that. Each team has their own system of play and philosophy. We aren't machines, we're not going to win for the rest of our lives. You learn from defeats, and there are some very difficult teams out there. Many years ago we went through some difficult times and came through a better team. Competition is good for sport, and for us too."
Ramos admitted that Iker Casillas was not enjoying the best of times after being left out of the Madrid side for the opening three games of the season, but said he also supported Diego López.
"I know Iker very well and this isn't an easy time for him. He is used to being the number one goalkeeper and has been for many years. I support Iker, but I also support Diego López, who is a great goalkeeper. But these decisions are not up to us. The most important thing to remember is that Real Madrid is more important than anything else."
