Veteran Spanish goalkeeper Iker Casillas said he always intended to remain at Porto after signing a new contract with the club.
Casillas was reportedly set to leave Estadio do Dragao after helping Porto to their first Primeira Liga title since 2012-13, but the Portuguese champions announced a one-year extension for the 36-year-old on Thursday.
"I am extremely happy to stay here for one more year. It's amazing to be linked to a fantastic club and city, both of which welcomed me from day one," said Casillas, who celebrates his 37th birthday on Sunday.
"There were rumours that I would leave, but I always intended to stay. Fortunately, I was able to do so, and I am happy for it.
"When I got to FC Porto, three years ago, the intention was to win the maximum number of titles possible. My arrival coincided with a less fortunate period for the club, but now that we got this important title, we need to enjoy it.
"And, at the same time, we need to start thinking of the coming season and the goal is to surpass what we did this year. We have the title in mind, as we have other national competitions, which are also important for a club as prestigious as is FC Porto."
