Casillas slams Kahn antics
Spain won the game in Mallorca 3-1 with goals from Casillas' Real team-mates Raul (2) and Guti, however Kahn's actions left the young shot-stopper fuming.
"As a goalkeeper he (Kahn) is very good, but as a person he leaves a lot to be desired," raged the 22-year-old.
"At times in life you have to be humble.
"I went to change my shirt with him, and he said no with a bad gesture.
"It seemed like he thought he was superior to me.
"You must always show manners, and even more so when you have lost 3-1."
Kahn is thought to be still holding a grudge after what he saw as a lack of respect from Real in the run up to their all-star centenary game in December which he eventually pulled out of.
