Orlando City SC striker Kaka has urged Iker Casillas to make a move to Major League Soccer next season, adding that the United States' top flight will soon be the best in the world.
Casillas, 34, played with Kaka at Real Madrid for four seasons, before the Brazilian left the Bernabeu to play for AC Milan again in 2013.
The Spaniard left Real to join FC Porto in the summer of 2015 and told Kaka he was interested in MLS, but that he still wanted to play in Europe for the time being.
"I would like Casillas to come [to MLS] next year, but he told me he wants to stay in Portugal and play a little bit," Kaka told Cadena Cope.
