The two defensive-minded players are included in Spain’s squad for World Cup qualifiers in the coming week against Finland and France, and Busquets thanked his Liga counterpart for saying he would like to bring the Blaugrana star to the Santiago Bernabeu.
"I am happy about this compliment and it means even more coming from someone like Sergio,” Busquets told reporters on Wednesday. “He is a great player and I would sign him too if I could."
Spain tops Group I on goal difference ahead of France, and Busquets insisted that it is essential for it to win Friday night’s “decisive” clash with Finland.
"We expect a game that is not going to be easy,” the Roja star continued. “We know how they play and they are a team that have plenty of good players. We will try to take advantage and win the game as it is one of the most decisive games [in qualification].
“There are still more games that we should win, but in football anything could happen. We're here to talk about the games and for us it's all good. [Our position] is well deserved, we do not want controversy.
“We're all in the same boat and we all fight for the same national team. We are partners and we don’t differentiate whether there’s a club rivalry or not.”
Following a clash with Finland, Spain will travel to France to play what could be a deciding game in Group I, although Busquets was keen to alleviate pressure on la Roja by hinting that the winner will not necessarily qualify top of the table.
"I don't know if it will be like a final against France, but it will certainly be a key game," he told a press conference on Wednesday.
"The team that gets the three points from that game will be very well positioned.
"We know that the game against Finland will not be easy. We have seen videos of them and they are a hard team. We hope to win so we have it all to play for against France."
