I think Pepe will stay in the summer whether we get CL or not, he seems to be happy at Liverpool. I dont think Torres had been happy for some time. I read that he wanted to leave since before the world cup. Not sure how true that is.
I personaly think Reina wants exactly the same things as Torres myself and thats win the games biggest honours, it must really hurt him everytime he turns up for Spain and talks to his best mates Puyol, Xavi and Inniesta. I would like to think Reina would stay but lets face it he is in exactly the same position as Torres in that he is playing for a Club who will never be able to provide him with that platform or if it ever does Reina will probably long since finished playing.
