Spain manager Vicente del Bosque believes Iker Casillas' decision to leave Real Madrid for Porto in the summer was "a great solution for an uncomfortable situation".
After 25 years with the Spanish giants that yielded several La Liga, Champions League and Copa del Rey trophies, as well as numerous others titles, Casillas found himself on the fringes at the Bernabeu with the club eventually deciding to release him at the end of last season.
Porto snapped up the 34-year-old on a free transfer and he has helped them to the top of the Primeira Liga standings with eight clean sheets.
"Porto was a great solution for an uncomfortable situation that Iker was having at a club he has represented since a kid and he gave them a great service," Del Bosque told O Jogo.
"At his age, I think it was a good move. He tells me he is happy, he is playing and he feels useful. He is still old enough to play at the highest level."
He added: "I watch almost every Porto game, and they are a team that dominate a lot, like Madrid in the Spanish league, and he is accustomed to be a goalkeeper of a big team."
