Alvaro Arbeloa, Fernando Torres, Xabi Alonso and Pepe Reina have all made Spain's squad.
"As a manager of an English club, to see your players in any national team is really important. To see so many of our players in the Spain squad - I think we must be really proud because it is a special situation and one which is really good for us.
"It means that we are bringing in players with quality who are good enough to play international football, so that is very positive.
"The four Liverpool players who have been selected have shown the quality that they have.
"We know that Iker Casillas is a very good goalkeeper but for me Pepe Reina is as good as him.
"Arbeloa will have his chance because he can play in more than one position and he has more experience now, and Xabi, as we know, is a top-class player who can be at the same level of the other midfielders.
"Finally, we have seen how good Torres can be during the last season.
"Spain has a lot of quality. Everyone talks about the fact that they have not won a major tournament but statistics like this are there to be broken - maybe this will be their time."
