Real Madrid's long-serving goalkeeper Iker Casillas labelled Fernando Torres "the most overvalued player in Spanish football" after the striker completed his £50 million move from Liverpool to Chelsea in January 2011.
This is according to Casillas's former Real Madrid teammate Jerzy Dudek, whose controversial new book alleges the revered keeper - after hearing Torres had signed for the Blues - commented: "He's the most overvalued player in Spanish football."
Casillas had won the 2008 European Champions and 2010 World Cup alongside Torres by that point and there always appeared to be a great deal of respect between the two players, despite the fact they are iconic figures of Madrid's two big rival clubs.

But Dudek's latest comments suggest Casillas was never a big fan of Torres the footballer, which is surprising because the former Liverpool striker was amongst the top three strikers on the planet for a brief period of time.
As it turned out, Torres bombed spectacularly at Chelsea, scoring a pitiful 20 league goals in 110 appearances following his big-money move to Stamford Bridge.

Fernando Torres will not regret Chelsea move
He now finds himself back at the Vicente Calderon, but will return to parent club AC Milan this summer. Atletico are not expected to sign Torres on a permanent deal after he scored just six goals in 26 appearances for his boyhood club.
Torres' fall from grace was remarkable - it seemed to happen almost overnight - but he still left Chelsea with three major titles to his name, compared to the zero he won with Liverpool.
The Spaniard, who was the joint-winner of the Euro 2012 Golden Boot, lifted the FA Cup and Champions League trophies in 2012 - and won the Europa League a year later.
So, while most people believe Torres made a mistake leaving Liverpool for Chelsea, he would beg to differ while pointing to his medal collection.
Torres, at his peak, was a sensational striker blessed with pace, power and a lethal eye for goal.
Casillas has yet to respond to the rumours published in Dudek's book, but it's safe to say he won't be overly impressed with his former Real Madrid team-mate for spilling the beans if the story is true.
