The shot-stopper is in fine form and he has spoken of all things Calcio.
Juventus are making the headlines for all the wrong reasons but Casillas doesn't believe it's the coaches' fault.
The European Championship winner believes too much demands are being made on the Tinkerman but he believes Juve can get out of the ruck they currently find themselves in.
"Too much is being asked from coach and team and it doesn't matter whether or not they have a competitive squad," the 'Keeper told La Gazzetta Dello Sport.
"The needs there are brutal and sometimes it's difficult to keep everything under control but they can do well."
The goalkeeper then turned his attentions back on the Cristiano Ronaldo saga and he has invited the Portuguese international to try again.
"Ronaldo? I think any great player always has the possibility to join Real Madrid," added Casillas.
"He doesn't even need to think about it, he should just accept."
Casillas also spared a thought for Milan, Inter and the potential Ballon d'Or winners as he gives his opinion on the headline makers.
"Mourinho? Inter have done well to take him. He is a good coach and everyone I know always speak highly of him," continued the Spaniard.
"He says what he likes but that doesn't make him a bad person. His ranting and raving is fun and the wage revelations was brilliant.
"Ronaldinho? He will need time to adapt and get back to his best but I think leaving Barcelona was neccessary for him.
"Ballon d'Or? [Lionel] Messi, [Marcos] Senna and [Fernando] Torres are my three candidates."
Juventus welcome the Madrid giants at the Olimpico and anything less than a win could see Ranieri being given the boot.
